M4 x 22mm Captive Socket Cap Head Screw | Similar to DIN 912 | A4 Stainless Steel
For laboratory equipment, instrumentation and technical enclosures, this M4 x 22mm captive machine screw provides a retained fastening format that can reduce loose screws during servicing or repeated access. The H3 hex socket gives positive tool engagement while the 7.0mm head diameter and 4.0mm head height follow a DIN 912-style cap head geometry. A4 Stainless Steel provides enhanced corrosion resistance for suitable outdoor, washdown, coastal and marine applications where a higher level of environmental resistance is required.
