Metric Socket Screws

Metric socket screws, also known as allen screws or allen bolts, are fasteners designed to be used with a corresponding allen wrench or hex key, which fit into a hexagonal recess. The hexagonal shape provides a secure grip and allows for high torque application during installation or removal.

They are typically high tensile, making them popular in many industries including manufacturing, engineering, automotive and construction.

Socket screw types include socket cap screw, socket button screw, countersunk (CSK) socket screw, socket set (grub) screw, and socket shoulder screws. They come in a variety of finishes including zinc, stainless, galvanised and unplated self colour.
