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. 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. This drive type has the disadvantage of not being as precisely controlled as can be obtained by proper use of a torque wrench; applications may still fail due to either too little torque being applied to correctly fasten the joint, or too much torque being required to shear the head, resulting in damage to the material being fastened.

A flathead screwdriver, also called a slotted screwdriver, is a tool with a wedge-shaped flat tip that is designed to fit into the notch on a slotted screw. These tools can come in various sizes and lengths, including oversized flathead screwdrivers that are useful in automotive work, standard-size screwdrivers for furniture construction, and precision flathead screwdrivers that are suitable for working on computers and other delicate electronics.

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.

Needs login A cross or double-slot screw drive has two slots, oriented perpendicular to each other, in the fastener head; a slotted screwdriver is still used to drive just one of the slots. This type is usually found in cheaply-made roofing bolts and the like, where a thread of 5mm (0.20in) or above has a large flattened pan head. The advantage is that they provide some measure of redundancy: should one slot be deformed in service, the second may still be used.The 12-spline flange screw drive has twelve splines in the fastener and tool. It consists of 12 equally spaced protrusions, each with a 60° angle. It is achieved overlaying 4 equilateral triangles, each one rotated 30° over the previous one. The spline drive was part of the obsolete, U.S-designed Optimum Metric Fastener System and was defined by ASTM B18.2.7.1M, which was withdrawn in 2011, [81] making the spline drive obsolescent. Unlike JIS, the ISO 4757 standard for cross-head screws does not specify a dot on the screw head. [33] Phillips II [ edit ] If you keep trying to drive a Y000 screw with a tool that doesn't grab well you'll strip the top of the screw and then you'll need to find a way to make a straight groove in the top which will allow you to remove the screw with a tiny slotted driver (flat head). There are a ton of problems that can arise as a result of this. Metal flakes can get lodged in between surface-mount components and do more damage to the device. Also you could slip and cause more damage. Etc. The Phillips Screw Company". phillips-screw.com. Archived from the original on 2021-10-08 . Retrieved 2021-10-07. Spanner-Bolts".
