0.6mm Y Shape Tri-Point Y000 Tri-Wing Screwdriver Tool Kit Compatible with Apple Watch Repair Opening Tool

Product Information

While a Phillips screwdriver has slightly tapered flanks, a pointed tip, and rounded corners, a Pozidriv screwdriver has parallel flanks, a blunt tip, and additional smaller ribs at 45° to the main slots. The manufacturing process for Pozidriv screwdriver bits requires a slightly more complex cutter than that for Phillips, however both can be manufactured in four cuts from a tapered blank.

Some consumer appliances, such as espresso machines from Jura Elektroapparate, use a proprietary screw head with an eccentric oval to dissuade owners from servicing their own machines. The carpenter screwdriver is made of a round rod and a flat tip. Its handle is flat on two sides (as shown in the figure). This enables the worker to exert full force or screwdriver. #15 Bolster Screwdriver Screwdriver bits". McMaster-Carr catalog (116thed.). p.2806. Archived from the original on 2019-12-14 .

Instead of twisting the screw with your wrist, you place the screw head against the screw and push it to tighten. Powered Screwdriver: This screwdriver is powered by electricity or a battery. Power drills with flat or Phillip’s heads are frequently used along with multi-bit screwdrivers.

Ratchet Screwdriver: Ratcheting screwdrivers feature an internal ball-bearing mechanism that makes turning the screw simple and repetitive. You can do this without taking out the screw’s driver head. Also known as an ECX or Combination Tip drive. A combined slotted and Robertson drive screw found in electrical power equipment and distribution equipment. The design allows for higher torque application with reduced camming, slipping out and damaging the fastener. [63] The ECX drive is not compatible with older combination Phillips and slotted head screws. [64] Although Milwaukee Electric Tool holds the trade name ECX, their marketing materials do not tell what type of screw head ECX is designed to fit. [50] Clutch [ edit ]

A combination slotted/hex head cap is often used for self-tapping screws for metal, where the hex head enables greater torque during the initial self-tapping installation, while allowing the convenience of a slotted screwdriver to be used for removal and reinsertion. The 12-pointed internal star shape superficially resembles the "double hex" fastener head, but differs subtly in that the points are shaped to an internal angle of 90° (derived from a square), rather than the 120° internal angle of a hexagon. In practice, drivers for the fasteners may be interchangeable, but should be examined carefully for proper fit before application of force. A hex key should not be used where a key of square cross-section is the correct fit. The polydrive screw drive, also known as RIBE, [74] is spline-shaped with rounded ends in the fastener head. The tool has six flat teeth at equal spacing; the sizes are determined by the diameter of the star points. Its primary advantage over older screw drives is that it resists cam out. It is used primarily in the automotive industry in high-torque applications, such as brakes and driveshafts.The triple-square, also known as XZN, is a type of screw drive with 12 equally spaced protrusions, each ending in a 90° internal angle. The name derives from overlaying three equal squares to form such a pattern with 12 right-angled protrusions (a 12-pointed star). In other words, three Robertson squares are superimposed at a successive 30° rotation. The design is similar to that of the double-square—in both cases, the idea being that it resembles a square (Robertson) but can be engaged at more frequent angles by the driver bit. These screws can be driven with standard Robertson bits. Hi-Torque slot drives were designed by Alcoa Fastening Systems, for situations where very high torque is needed, along with the ability to repeatedly install and remove the fastener. [7] The design features curved walls, unlike the straight-walled slot drive. The Phillips screw drive (specified as an ANSI Type I Cross Recess [9] and type H in ISO documentation) was created by John P. Thompson, who, after failing to interest manufacturers, sold his design to businessman Henry F. Phillips. [10] [11] Phillips is credited with forming a company ( Phillips Screw Company), improving the design, and promoting the adoption of his product. [10] The original 1932 patent [12] expired in 1966, but the Phillips Screw Company continued to develop improved designs. [10] MTI Catalog" (PDF). moodytools.com.
