M5 x 85mm Captive Socket Cap Head Screw | Similar to DIN 912 | A4 Stainless Steel
Providing a retained fixing for manufacturing equipment, jigs and maintenance panels, this M5 x 85mm 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.
What Are Captive Socket Cap Head Screws?
Captive Socket Cap Head Screws are specialist fasteners designed to stay attached to a panel, cover or component after the threaded portion has been loosened. A reduced captive section works with a compatible panel, washer, sleeve or retaining feature so the screw can remain retained instead of falling free.
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.
