M30 Unbrako Socket Head Cap Screws ISO 4762 in Black Oxide Class 12+ High Tensile Steel

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. Please note that due to the nature of the surface finish on Unbrako products, some surface corrosion may be evident. This does not affect the performance of the product. Property class of 12.9.
