DIN 912 / ISO 4762 socket head cap screws made from A4 stainless steel. These metric socket cap screws feature a cylindrical head and internal hex socket drive for machinery, equipment assembly, maintenance, repair and corrosion-resistant fastening applications.

A4 stainless steel provides improved corrosion resistance compared with plain steel and A2 stainless steel, making it a strong choice for marine, outdoor, food processing, chemical, washdown and other demanding environments where moisture or corrosion exposure may be present.

DIN 912 / ISO 4762 screws are also known as Allen screws, socket cap screws, metric socket screws or socket head cap screws. The internal hex drive allows installation in recessed or tight-clearance areas where a standard external hex head may not fit.
