M5 x 20mm Captive Socket Cap Head Screw | Similar to DIN 912 | A2 Stainless Steel
Providing a retained fixing for automation systems, machine covers and removable guards, this M5 x 20mm retained socket cap screw combines a hex socket cap head with a purpose-designed captive diameter. The format helps keep the screw with the assembly during inspection, adjustment or maintenance when used with a compatible retention method. 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
- 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.
