M8 x 40mm Captive Socket Cap Head Screw | Similar to DIN 912 | A4 Stainless Steel
This M8 x 40mm stainless steel captive screw is suited to industrial equipment, fabricated housings and service access points where removable panels must be opened without completely separating the fastening hardware. The 1.25mm pitch, H6 drive and 16.0mm 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?
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
- 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.
