A machine screw is a specialized type of screw used primarily in electronic and mechanical hardware assembly. Machine screws come in various head styles, sizes, and lengths to accommodate machines with many components
Hexagon socket screws are suitable for occasions where the installation space is small or the head of the screw needs to be buried.
Socket cheese head screws to DIN 912, often referred to as allen head bolts, have a hexagonal recess and are driven using a hex wrench or insert bit. This makes these screws much more efficient than standard slotted screws as the hex socket drive has more resistance to cam out and can be used with power drivers enabling faster use and higher torque to be achieved.
Socket cap screws, also known as socket head capscrews or allen bolts, are a screw with a cylindrical head and hex socket drive and are a most commonly a high strength fastener used in the most demanding applications.
