M4 x 50mm Captive Socket Cap Head Screw | Similar to DIN 912 | A4 Stainless Steel
Made for repeat-access assemblies, this M4 x 50mm cap head captive screw uses a reduced 3.0mm section between the threaded portion and head area. When paired with a compatible captive feature, this allows the fixing to remain with the panel after disengaging from the mating thread. 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
- 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.
