The material of this screw is stainless steel, the groove is hex socket, and the head is button. Socket screws are a type of screw designed and manufactured with a hexagonal internal drive built into the head. As such, they are intended to be tightened and loosened with an Allen wrench or hex key, as opposed to a traditional screwdriver. This is the key feature that sets a socket screw apart from other screw head drive styles such as the Phillips head screw, slotted and flathead screws, and Pozidriv screws.

Features

The potentially higher torque and clamping force that can be achieved with a socket screw over a regular screw makes them a preferable option in some applications. When compared to regular screws and bolts in a like for like test, socket screws can often deliver some or all of the following advantages in relevant scenarios:

Since socket screws typically offer greater clamping force than standard screws and many other small-format fastener types, fewer socket screws can be used in a given application to achieve the same overall clamping force on the joint or workpiece.
