Supadrive allow a small angular offset between the screw and the screwdriver. Pozidrive have to be directly in line" The JIS B 1012 [29] was commonly found in Japanese made equipment, such as cameras and motorbikes. Superficially it looks like a Phillips screw with narrower and more vertical slots, to give less tendency to cam out. The bottom of the recess is flat, and the point of the driver has to be blunt. A Phillips screwdriver has the same 26.5 degree cone angle but because of the tapered slots will not seat fully, and will damage the screw if forced. The applicable standards that govern the Torq-set geometry are National Aerospace Standard NASM 33781 and NASM 14191 for the ribbed version. The ribbed version is also known as ACR Torq-set.

The Supadriv (sometimes spelled incorrectly as "Supadrive") screw drive is very similar in function and appearance to Pozidriv. It is a later development by the same company. The description of the Pozidriv head applies also to Supadriv. 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. Pozidriv and Supadriv screws are slightly different in detail; the later Supadriv allows a small angular offset between the screw and the screwdriver, while Pozidriv has to be directly in line.

The pentalobe screw drive is a five-pointed tamper-resistant system implemented by Apple in its products. [43] Apple's first use of the pentalobe drive was in mid-2009 to secure the battery in the MacBook Pro. Smaller versions are now used on the iPhone 4 and subsequent models, the MacBook Air (since the late 2010 model), the MacBook Pro with Retina Display and the 2015 MacBook. Pentalobe screw sizes include TS1 (also known as P2 or 0.8mm, used on the iPhone 4 and subsequent models), TS4 (also known as P5 or 1.2mm, used on the MacBook Air [since late 2010], the MacBook Pro with Retina Display and the 2015 MacBook) and TS5 (also known as P6 or 1.5mm, used on the 2009 MacBook Pro battery). The TS designation is ambiguous as it is also used for a Torq-set screw drive. Screwdriver bits". McMaster-Carr catalog (116thed.). p.2806. Archived from the original on 2019-12-14 .

"Goodwin's Hollow Safety Set Screw" Hardware Dealers' Magazine. pp. 846 V, 865, 1090 A U-drive screw has a helical thread with an angle acute enough to be driven by a hammer or pressure from an arbor press, and thus has a domed head with no means of turning it. [92] These are most frequently driven into plastics with a pre-drilled pilot hole.The Phillips/square screw drive, also known as the Quadrex, Pozisquare screw drive, is a combination of the Phillips and Robertson screw drives. While a standard Phillips or Robertson tool can be used, there is also a dedicated tool for it that increases the surface area between the tool and the fastener so it can handle more torque. [62] Recex [ edit ] 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.

The double-square drive is two squares superimposed at 45° rotation, forming an 8-pointed star. The design is similar to a square drive (Robertson), but can be engaged at more frequent angles by the driver bit.
