M10 x 40mm Captive Socket Cap Head Screw | Similar to DIN 912 | A4 Stainless Steel
For automation systems, machine covers and removable guards, this M10 x 40mm socket head captive screw provides a retained fastening format that can reduce loose screws during servicing or repeated access. The H8 hex socket gives positive tool engagement while the 16.0mm head diameter and 10.0mm head height follow a DIN 912-style cap head geometry. 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?
Cap Head Captive Screws combine a DIN 912-style socket cap head with a reduced section intended for captive retention. They are useful on equipment that requires repeated access because the screw can remain with the removable part during servicing which reduces the chance of loose fixings being dropped or misplaced.
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.
