M4 x 25mm Captive Socket Cap Head Screw | Similar to DIN 912 | A2 Stainless Steel
This M4 x 25mm socket head captive screw is designed for automation systems, machine covers and removable guards where the fixing needs to remain attached after it has been loosened. The 8.0mm threaded length provides the fastening section while the reduced 3.0mm captive diameter is intended to work with a compatible panel, washer, sleeve or retaining feature. 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
- Industrial Enclosures: Provides a retained fastening point for covers and doors on suitable equipment housings.
- Instrumentation: Keeps small fastening hardware attached to precision panels, test equipment and technical housings.
- Automation Equipment: Supports repeat-access panels on machinery, control systems and production equipment.
- Transport Equipment: Provides retained fixings for suitable removable covers and inspection panels.
