M3 x 50mm Captive Socket Cap Head Screw | Similar to DIN 912 | A4 Stainless Steel
Providing a retained fixing for machinery guards, equipment covers and service panels, this M3 x 50mm stainless steel captive screw combines a hex socket cap head with a purpose-designed captive diameter. The format helps keep the screw with the assembly during inspection, adjustment or maintenance when used with a compatible retention method. 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 Socket Cap Head Screws are specialist fasteners designed to stay attached to a panel, cover or component after the threaded portion has been loosened. A reduced captive section works with a compatible panel, washer, sleeve or retaining feature so the screw can remain retained instead of falling free.
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.
