Socket screws are threaded fasteners with a cylindrical head and internal hex drive. They are installed using an Allen wrench or hex key and are valued for their high torque strength, compact head profile and clean appearance. Socket screws are commonly used when external wrenching clearance is limited.

What Are Low-Head Socket Cap Screws?
A low-head socket cap screw, also known as a low-profile socket cap screw, is a type of fastener used in mechanical applications. It has a hexagonal socket drive and a cylindrical head with a reduced height compared to standard socket cap screws. This reduced head height allows the screw to sit flush or nearly flush with the surface it is fastening, making it ideal for applications where space or clearance is limited.
These screws are often used in situations where a standard socket cap screw would interfere with other components or where a lower profile is desired. Note that due to their reduced head height and smaller socket size, low-head cap screws cannot be preloaded as high as standard socket head cap screws. These fasteners are not suitable for handling dynamic loads.
