Product information

These black socket button screws are made out of A2 304 stainless steel material with a matt black finish to ISO 7380 and have a metric coarse thread. They are sometimes known as Socket round head or dome head Screws. They have a hexagonal recessed drive. A hex key ( sometimes referred to as an Allen wrench or Allen key) or hex driver is required to tighten or loosen a socket screw. Socket screws are commonly used in assemblies that do not provide sufficient clearance for a conventional wrench or spanner. These low profile rounded head screws are often used for their aesthetic qualities.
