M12 x 40mm Captive Socket Cap Head Screw | Similar to DIN 912 | A4 Stainless Steel
Designed for industrial equipment, fabricated housings and service access points, this M12 x 40mm retained cap head screw combines a socket cap head with a reduced captive section. Once installed with a suitable retaining feature, the screw can be loosened from its mating thread while remaining associated with the panel or component. A4 Stainless Steel provides enhanced corrosion resistance for suitable outdoor, washdown, coastal and marine applications where a higher level of environmental resistance is required.
