M8 Torx Head Cap Screws ISO 14579 (sim. DIN 912) in A2 Stainless Steel

A Torx Key (6 Lobe) driven example of the more familiar Socket Head Cap Screw, these are a more modern alternative standard machine fastener to the standard hexagon headed bolt or setscrew, as found on much modern machinery. A Torx key (6 lobe) is required to fit these fasteners and gives a much more secure drive allowing for more torque and a surer tightening feel. Conforming to ISO 4762 or DIN 912, the contact surfaces of this screw or bolt are protected from external damage. Generally manufactured with a partial thread beyond a certain length and nominal diameter combination, but occasionally some stock may include a fully threaded shank at the same combination. Ideal for uses where there is little room or clearance for securing.
