M4 x 50mm Captive Socket Cap Head Screw | Similar to DIN 912 | A2 Stainless Steel
This M4 x 50mm cap head captive screw is suited to modular equipment, access doors and maintenance assemblies where removable panels must be opened without completely separating the fastening hardware.

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
- 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.
