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](https://uk.rs-online.com/web/content/discovery/ideas-and-advice/socket-screws-guide).

RS offer an extensive range of high-quality threaded fixings with standard metric threads and UNC (Unified National Coarse) threads.

### Head Shapes
- **Hex Socket Button** - has a larger head diameter making them more appropriate for holding thin materials such as sheet metal guards.
- **Hex 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.
- **Hex Socket Countersunk** - used when you need a screw to fit flush or below the surface of your material.
- **Hex 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.

#### When would I use a Socket Screw?
