M3 x 45mm Captive Socket Cap Head Screw | Similar to DIN 912 | A2 Stainless Steel
Designed for manufacturing equipment, jigs and maintenance panels, this M3 x 45mm retained socket cap 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?
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.
