M5 x 25mm Captive Socket Cap Head Screw | Similar to DIN 912 | A4 Stainless Steel
Providing a retained fixing for transport equipment, inspection panels and removable covers, this M5 x 25mm retained socket cap 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.
What Are Captive Socket Cap Head Screws?
Cap Head Captive Screws combine a DIN 912-style socket cap head with a reduced section intended for captive retention. They are useful on equipment that requires repeated access because the screw can remain with the removable part during servicing which reduces the chance of loose fixings being dropped or misplaced.
Common Applications
- Jigs and Fixtures: Keeps adjustment or access fasteners associated with suitable workshop fixtures and production tooling.
- Laboratory Equipment: Supports retained panel fixing on instruments and serviceable technical equipment.
- Fabricated Housings: Provides a captive fastening format for custom covers, guards and equipment enclosures.
- General Engineering: Useful where a screw needs to remain attached to the assembly after disengaging from its mating thread.
