Black Stainless Steel Low Head Socket Cap Head Bolts Our low head socket cap head bolt are manufactured using A2 grade stainless steel (304) to DIN 7984 specification. They're finished with our very own CB10 black oxide coating - delivering a permanent, black corrosion-resistant, cap head bolt that look superb and will give years of service.
A low profile head with serious holding power The cylindrical cap low head and internal hex socket are what define this bolt - the low head sits proud of the surface with a neat, low compact profile, and the hexagon socket allows high torque to be applied with a standard Allen key or hex bit, giving a secure and reliable fixing in even the most demanding of places.
Our CB10 black stainless low head socket cap head bolts are a firm favourite across production line builds, custom fabrication, roll cages, project assemblies, and motorsport applications - in fact just about anywhere a strong, recessed black fixing contributes to the finished aesthetic.
Why use CB10 black stainless eners? Painted black eners look ok in the packet - but often chip the moment an Allen key touches the socket, or can start to flake within weeks of any outdoor or high-humidity exposure. The CB10 black finish is chemically bonded directly to the stainless steel surface. It isn't a coating sitting on top waiting to be damaged - it's actually part of the bolt. If you're looking for a cap head bolt that performs in tough environments and still looks fantastic years down the line, 'congrats' you've found it.
