M8 x 20mm Captive Socket Cap Head Screw | Similar to DIN 912 | A4 Stainless Steel
Providing a retained fixing for general engineering applications requiring retained fasteners, this M8 x 20mm socket captive screw combines a hex socket cap head with a purpose-designed captive diameter. The format helps keep the screw with the assembly during inspection, adjustment or maintenance when used with a compatible retention method. A4 Stainless Steel provides enhanced corrosion resistance for suitable outdoor, washdown, coastal and marine applications where a higher level of environmental resistance is required.
