Square: Jul 07, 2015 Such types of fasteners either feature a hexagonal recession in the head or do not have grooves at all. The hex socket screw /Allen screw requires an Allen wrench, featuring a hexagonal shaft and the other type of hex screw’s herepletely hexagonal in shape. A socket wrench is required to tighten or loosen it. Overview Slotted drives Cruciform drives Square drives Multiple-square drives Internal hex drives A screw drive is a system used to turn a screw. At a minimum, it is a set of shaped cavities and protrusions on the screw head that allows torque to be applied to it. Usually, it also involves a mating tool, such as a screwdriver, that is used to turn it. The following heads are categorized heremonality, with some of heremon drives being classified as tamper-resistant. heree in a range of sizes, typically distinguished by a number, such as Phillips #00.

Metric screws are specified with the letter “M,” the diameter, then the thread pitch. So “M6 1” would be a 6mm diameter screw with a thread pitch (spacing between threads) of 1mm. Unified National threads, also known as “English” or “Imperial,” are defined by the screw number — 10 for example, signifying a .190″ diameter — and threads per inch. So a 10-32 screw is a #10 (.190″).
