screwdriver bits types

Tamper-resistant drives are commonly used on equipment such as home electronics, to prevent easy access thereby reducing the incidence of damage, improper repairs or repairs by people without the relevant technical knowledge. A version with left-hand threads is called an Opsit screw, where unscrewing can be done by turning the screwdriver clockwise, which is the opposite of tri-wing and regular screws.[79][80]. The Type II (Conical/Connie) design adds a conical cup that receives a centering pin on the driver, improving the alignment of the driving tool to the fastener recess.

Philips bits look very much like a cross, and come in a range different sizes – #000, #00, #0, #1, #2, #3 and #4 (#2 is the most common). There’s really 2 things you need to know to use a screwdriver – the types of screwdrivers and the types of screw drives. The most common sizes in use for consumer electronics are DCT-20 and DTC-27. The bottom of the recess is flat, and the point of the driver has to be blunt. Variants with a pin in the center are often found in game systems, to discourage improvised attempts to use a slotted screwdriver to drive the fastener. There are various other ways to categorize screw drives. Insert Bits – compact bits that are economical, change over quickly and require less storage space. There are many different types of screw driver bits available on the market, but here is an overview of the most common. [24][27][28], In detail, the Supadriv screwhead is similar to Pozidriv but has only two identification ticks, and the secondary blades are larger. A further improvement over Torx Plus.[50]. "JIS" standardized cruciform-blade screwdrivers are available for this type of screw, and should always be used to avoid head and driver damage. Unlike the "tri-point" fastener, the slots are offset, and do not intersect the center of the fastener. Recent widespread availability of assorted drive bits (including security types) minimizes this advantage, at least for some fastener types. These bits can be found in sizes #1, #2 and #3. In this case, the nutsetter you require may be in metric (i.e. The Phillips screw design was developed as a direct solution to several problems with slotted screws: increased cam out potential; precise alignment required to avoid slippage and damage to driver, fastener, and adjacent surfaces; and difficulty of driving with powered tools. If you have an impact driver, you should use impact-rated bits as other bit … Note: Not all screwdriver bits are interchangeable. Double ended bits feature a screwdriver bit on either end (either the same or different types). A double slotted screw drive is not considered cruciform because the shape is not recessed, and consists only of two superimposed simple milled slots. Note that it is this typical chisel shape which allows 9 screwdriver sizes to drive 24 different slotted screw sizes, with the drawbacks of not fitting as closely as a hollow-ground screwdriver would, and increasing the possibility of damaging the fastener or surrounding area.

[51], The Phillips/square screw drive, also known as the Quadrex, Pozisquare screw drive, is a combination of the Phillips and Robertson screw drives. Socket adaptors give you the ability to attach sockets to a drill, allowing you to tighten nuts or screws that are too big for nutsetters. In many countries it is commonly but incorrectly called "imbus". Double hex is a screw drive with a socket shaped as two coaxial offset hex recesses; it can be driven by standard hex key tools. In other words, three Robertson squares are superimposed at a successive 30° rotation. It was designed to permit increased torque transfer from the driver to the bit compared to other drive systems. They are ideal for handling the torque on applications where impact drivers are used. It is a tamper-resistant style of screw drive, and is most frequently used for aerospace applications. It is achieved overlaying 4 equilateral triangles, each one rotated 30° over the previous one. It is designed to be a lightweight, low-profile and high-strength drive, with full contact over the entire recess wing, reducing risk of stripping. Robertson screwdrivers are easy to use one-handed, because the tapered socket tends to retain the screw, even if it is shaken. "What is the Difference: Screw Bits – Phillips vs. Pozidriv", "Means for uniting a screw with a driver", "What are the differences between the two types of drive – Phillips and Posidriv®? An alternative design leaves a low-profile button head visible after installation. Most of the following screw drives are considered tamper-resistant because of their obscurity. An External Torx version exists, where the screw head has the shape of a Torx screwdriver bit, and a Torx socket is used to drive it. Key-Rex screws are another design, and are used in such things as ballot boxes and bank vaults.[42]. Coin-slot drives are so-called because of the curved bottom of the recess, which facilitates driving them with a suitable coin. The ASTER recess was designed by LISI Aerospace[46] to provide a more reliable solution than the hexagonal recess for assemblies of composite structures on aircraft. There are many types of electric screwdriver. [52], The Recex drive system claims it offers the combined non-slip convenience of a Robertson drive during production assembly and Phillips for after market serviceability. Nutsetters are similar to a hex bit, except they fit over their corresponding screws (in this case, tek-screws), rather than into them. A thumbscrew is a type of screw drive with either a tall head and ridged or knurled sides, or a key-like flat sided vertical head. It consists of 12 equally spaced protrusions, each with a 60° angle. The slotted screw is commonly found in existing products and installations, along with use in simple carpentry work and in applications where minimal torque is needed. This ring sits just below the end of the phillips bit and upon screw driving, the ring presses up against the material and stops the screw from being driven below the material’s surface. TP3 (sometimes referred to as tri-lobe or tri-lobular) uses a Reuleaux triangle-shaped recess in the screw head, to make it semi-secure because it cannot be driven by a flat-blade screwdriver[78] and is not readily driven, as Tri-angle is, by hex keys. Because of this, a regular Phillips or flat-blade screwdriver will not fit the head. Power Bits – fit directly into the power tool or quick change chuck for improved concentricity and easier clearance. These sizes roughly correspond to the Phillips head numbers. Screwdriver is invented in the 15th century and through the centuries it became the essential tool in every toolbox. [13]:85–86 They also allow for the use of angled screw drivers and trim head screws. [9] The original patent[11] expired in 1966, but the Phillips Screw Company continued to develop improved designs.[9]. Some of these types are specified in ISO 4757, Cross recesses for screws. There are three styles of screwdriver bits available. While each has its own driver,[26] the same screwdriver heads may be used for both types without damage; for most purposes it is unnecessary to distinguish between the two drives. Screwdriver bit materials . Phillips screwdriver bits are among the most widely used of all types today. The Reed & Prince Mfg. Contact Us Call our Service Hotline or use our contact form. Torx bits are shaped like a 6-sided star and are used on anything from cars to consumer electronics. [citation needed] The term "inbus" is derived from Innensechskant Bauer u. Schaurte (German: "Inner 6-edge Bauer & Schaurte"), analogous to the US term "Allen key". In the present day it is usually seen on electronics equipment. They are used with a bit holder. The tool used to drive a slot is called a common blade, flat-blade, slot-head, flat-tip[3] or flat-head / flathead[4] screwdriver. ACR Phillips II Plus is a screw-drive design that can be driven by a #2 Phillips driver or a #2 Robertson driver, but when driven by a Phillips II Plus Bit, the combination results in a stick-fit interface. This recess is optimized to fit on the threaded end of aerospace fasteners. [citation needed]. Screwdriver Types, find quality Screwdriver Types products,Screwdriver Types Manufacturers, Screwdriver Types Suppliers and Exporters at ZHIDA Hardware CO.,LTD. The hexalobular socket screw drive, often referred to by the original proprietary brand name Torx ( /ˈtɔːrks/) or by the alternative generic name star drive, uses a star-shaped recess in the fastener with six rounded points. Linear broaching to cut corners into a drilled hole (similar to the action of a mortising machine for woodworking) has also been used (less commonly) over the decades. Some of these types are specified in ISO 4757, Cross recesses for screws. instead of a 3/8” (9.38mm) nutsetter, you may need a 10mm). Additionally, it is unique compared to other common drives, due to it being straightforward to manufacture the slot head, and the ability to be driven by a simple handtool. Torx Plus is an improved version of Torx that extends tool life even further and permits greater torque transfer compared to Torx. They are commonly found on German vehicles such as BMW, Opel, Mercedes, Porsche and those from the Volkswagen Group (Audi, Seat, Skoda, and Volkswagen).[43]. These sizes do not necessarily describe a particular dimension of the drive shape, but rather are arbitrary designations. [37][38][39] Robertson's refusal to license his screws prevented their widespread adoption in the United States, where the more widely-licensed Phillips head gained wider acceptance. Basically an allen key that you can put in your drill, these hex bits are commonly used when assembling DIY furniture and for locations where surrounding obstacles limit allen key access. The German company Bauer & Schaurte patented the hex socket 1936 in Germany, and marketed products based on it. Slotted screwdriver bits . They are security bits, and come in sizes #4, #6, #8 and #10. Standard 12-point hex socket bits and wrenches fit these screws. Double ended bits feature a screwdriver bit on either end (either the same or different types). They resist cam-out better than Phillips or slotted bits, and were specifically designed with this purpose in mind due to the improvements in torque-limiting automatic screw driving tools. There are probably still more slotted or ‘flathead’ screws and screwdriver bits in overall circulation, but those are often a result of older standards not being updated, and are largely seen as something of a legacy design by modern standards. Informationen, die über diese Service Cookies gewonnen werden, können möglicherweise auch zur Seitenanalyse weiterverarbeitet werden. This type of screw head is commonly used in the manufacture of mobile homes and recreational vehicles. Dzus fasteners, which have a cam-lock body instead of a threaded body, use a slot drive. It is designed to be intrinsically incompatible with many tools. There are specialty fastener companies that make unusual, proprietary head designs, such as Slot-Lok and Avsafe. The most common of these are a combination of a slotted /Phillips head, often used in attaching knobs to furniture drawer fronts and combined slotted/pozidriv heads which are so ubiquitous in electrical switchgear to have earned the nickname "electrician's screws". Screwdriver Bits. Hex-head screws are small in size and commonly found in doorknobs, towel bars, and in some mechanical installations. [26], Phillips II recesses are compatible with Phillips drivers, but have a vertical rib in between the cruciform recesses that interacts with horizontal ribs on a Phillips II driver to create a stick-fit, and to provide anti cam-out properties (the ribs are trademarked as "ACR" for Anti Cam-out Ribs). For this reason Bristol screw drives are often used in softer, non-ferrous metals. Company of Worcester, Massachusetts, was put into bankruptcy in 1987 and liquidated in 1990. The knife and gun manufacturer Microtech uses a variation of this with 3 round holes arranged in a triangle shape. aircraft.
