M3 x 16mm Captive Socket Cap Head Screw | Similar to DIN 912 | A4 Stainless Steel
Made for repeat-access assemblies, this M3 x 16mm retained cap head screw uses a reduced 2.2mm section between the threaded portion and head area. When paired with a compatible captive feature, this allows the fixing to remain with the panel after disengaging from the mating thread. 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.
