M3 x 22mm Captive Socket Cap Head Screw | Similar to DIN 912 | A2 Stainless Steel
This M3 x 22mm captive machine screw is suited to general engineering applications requiring retained fasteners where removable panels must be opened without completely separating the fastening hardware. The 0.50mm pitch, H2.5 drive and 6.0mm threaded length provide the main installation details for the screw. 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
- Machinery Guards: Keeps compatible screws attached to removable guards during inspection, adjustment and maintenance.
- Control Cabinets: Retains panel fixings on electrical and automation enclosures that require repeated access.
- Equipment Covers: Supports serviceable covers where loose screws could be dropped inside machinery or misplaced.
- Maintenance Panels: Helps keep fastening hardware associated with access panels during routine servicing.
