M12 x 55mm Captive Socket Cap Head Screw | Similar to DIN 912 | A2 Stainless Steel
For laboratory equipment, instrumentation and technical enclosures, this M12 x 55mm retained socket cap screw provides a retained fastening format that can reduce loose screws during servicing or repeated access. The H10 hex socket gives positive tool engagement while the 18.0mm head diameter and 12.0mm head height follow a DIN 912-style cap head geometry. 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 Cap Screws are used where a conventional fully removable screw could create a loose-part risk during maintenance. Their reduced captive diameter allows a suitable retention feature to hold the screw to the panel while the threaded end engages and disengages from the mating component.
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.
