Socket head cap fasteners

A socket cap fastener, also known as a socket screw or an Allen bolt, has a cylindrical head and hexagonal drive hole. Socket head cap fasteners are often used in die fixturing, clamping or machine parts. They are an excellent option for those difficult to get to fasteners where maneuvering wrenches can be problematic.

High strength and corrosion resistance

As carbon steel fasteners are susceptible to corrosion, engineers have traditionally opted to use stainless steel fasteners in corrosive environments. However, problems were often encountered in applications that also required high strength as standard stainless steel fasteners do not offer the same strength class as carbon steel for example.

BUMAX stainless steel fasteners are a game changer for demanding applications as they combine high strength with corrosion resistance. This makes BUMAX stainless steel socket head cap fasteners the optimal choice for applications that require both corrosion resistance and high strength.

Customer case story: Cleaning equipment for oil and gas wells

BUMAX DX 129 socket head cap fasteners are used to fasten sub-sea equipment for cleaning oil and gas wells. Regularly using such equipment to clear wells of debris is essential in optimizing production and avoiding potentially costly issues.

BUMAX DX 129 fasteners were selected as they are the only fastener solution capable of dealing with the extreme sub-sea environments – including very high temperatures and pressures, combined with exposure to saltwater and hydrogen sulfide. DX 129 also ensures a strength class of 12.9, which is essential in this extreme environment.
