M5 x 55mm Captive Socket Cap Head Screw | Similar to DIN 912 | A4 Stainless Steel
Designed for manufacturing equipment, jigs and maintenance panels, this M5 x 55mm captive cap screw combines a socket cap head with a reduced captive section. Once installed with a suitable retaining feature, the screw can be loosened from its mating thread while remaining associated with the panel or component. 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.
