M8 x 40mm Captive Socket Cap Head Screw | Similar to DIN 912 | A2 Stainless Steel
Made for repeat-access assemblies, this M8 x 40mm captive hex socket screw uses a reduced 6.2mm 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. 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.
