M8 x 55mm Captive Socket Cap Head Screw | Similar to DIN 912 | A4 Stainless Steel
Made for repeat-access assemblies, this M8 x 55mm captive machine screw uses a reduced 6.2mm section between the threaded portion and head area. When paired with a compatible captive feature, this allows the fixing to remain with the panel after disengaging from the mating thread. A4 Stainless Steel provides enhanced corrosion resistance for suitable outdoor, washdown, coastal and marine applications where a higher level of environmental resistance is required.
