M4 x 25mm Captive Socket Cap Head Screw | Similar to DIN 912 | A4 Stainless Steel
Made for repeat-access assemblies, this M4 x 25mm retained cap head screw uses a reduced 3.0mm 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.
