M3 x 20mm Captive Socket Cap Head Screw | Similar to DIN 912 | A4 Stainless Steel
This M3 x 20mm retained socket cap screw is suited to control cabinets, electrical enclosures and access plates 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. A4 Stainless Steel provides enhanced corrosion resistance for suitable outdoor, washdown, coastal and marine applications where a higher level of environmental resistance is required.
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.
