Unbrako Socket Head Cap Screws ISO 4762 M20mm in Black oxide high tensile steel class 12+

Also known as an Allen screw or Allen bolt, or simply a cap screw. Socket Head Cap screws are a more modern alternative standard machine fastener to the standard hexagon headed bolt or setscrew, as found on much modern machinery. A hex key (otherwise known as an Allen key) is required to fit these fasteners. Conforming to ISO 4762 or DIN 912, the contact surfaces of this screw or bolt are protected from external damage. UNBRAKO® branded and manufactured to be stronger than the other size for size high tensile versions. Includes a precision hex socket for maximum key engagement. Property class of 12.9.
