M8 x 45mm Captive Socket Cap Head Screw | Similar to DIN 912 | A4 Stainless Steel
For general engineering applications requiring retained fasteners, this M8 x 45mm captive cap screw provides a retained fastening format that can reduce loose screws during servicing or repeated access. The H6 hex socket gives positive tool engagement while the 13.0mm head diameter and 8.0mm 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.
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.
