Fixaball UNC 5/16" Socket Screw Button High Tensile 10.9 Self-Colour

For low-profile fastening, the Fixaball UNC 5/16" socket screw button combines a rounded button head with a hex socket drive. Made from high tensile steel grade 10.9 with a self-colour finish, it suits applications where a smooth head profile is preferred and no exposure to moisture is expected.

These screws are available in a range of lengths, with all measurements taken from the underside of the head. The self-colour finish is black with no surface treatment, and corrosion resistance is low without further surface treatment. Typical use includes dry conditions and applications where the screw is often greased or oiled.
