M5 x 18mm Captive Socket Cap Head Screw | Similar to DIN 912 | A2 Stainless Steel
Designed for instrument housings, test equipment and precision assemblies, this M5 x 18mm captive socket cap head screw combines a socket cap head with a reduced captive section. Once installed with a suitable retaining feature, the screw can be loosened from its mating thread while remaining associated with the panel or component. A2 Stainless Steel provides good corrosion resistance for general engineering, machinery, equipment and indoor or suitably protected external applications.
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.
