Socket Screws

Socket screws have a cylindrical head and an internal hex drive. They are used when externally wrenched fasteners are not practical because of a lack of space. Socket screws are tightened using an Allan or Hex key. Discover everything you need to know in our socket screws guide.
RS offer an extensive range of high-quality threaded fixings with standard metric threads and UNC (Unified National Coarse) threads. /ph2Head Shapes/h2pHex Socket Button - has a larger head diameter making them more appropriate for holding thin materials such as sheet metal guards./ppHex Socket Cap - Socket cap screws have a head height equal to the shank diameter. They are used instead of a hex bolt when there is less clearance available./ppHex Socket Countersunk - used when you need a screw to fit flush or below the surface of your material./ppHex Socket Shoulder - often used as a pivot point or axis because shoulders are ground to a tight tolerance. They feature a small cylindrical head with tall vertical sides./ph3What are the different types of materials available?/h3pOur socket screws are available in a range of materials to suit every application and environment.

The cylindrical heads of socket screws require less space than hex heads and require no additional wrench space./p
