Value Collection FHS1X0305-050BX M3x0.5 Flat Socket Cap Screw

Product Description

The VALUE COLLECTION FHS1X0305-050BX is a metric flat socket cap screw designed for applications where a flush or countersunk fastener profile is required. Built to DIN 7991, this M3x0.5 screw features a 90-degree flat head and a 2.00 mm hex socket drive, allowing installation with a standard hex key. The screw is fully threaded over its 5.00 mm overall length and manufactured from 18-8 austenitic stainless steel to Grade A2, providing solid corrosion resistance in wet, chemical, or outdoor environments. This fastener is sold in a minimum order quantity of 50 pieces and is suited for precision assemblies, enclosures, panels, and mechanical sub-assemblies across HVAC, electrical, and plumbing equipment service work.

This flat socket cap screw is used wherever a low-profile, flush-mount fastener is needed in metric-threaded assemblies. The countersunk 90-degree head seats cleanly into chamfered holes, keeping mating surfaces unobstructed. Typical applications include equipment panels, junction boxes, access covers, pump housings, and light structural brackets found in residential and commercial mechanical systems. The A2 stainless steel construction makes it appropriate for corrosive or high-humidity service environments. Electricians, HVAC technicians, and plumbers routinely use fasteners of this type when reassembling or fabricating equipment enclosures and mounting hardware.

Compatibility

Designed for use in any M3x0.5 metric-threaded application requiring a DIN 7991 countersunk flat socket cap screw in 18-8 stainless steel.

Installation Notes

Install using a 2.00 mm hex key or matching bit driver. Ensure the mating hole is chamfered to a 90-degree angle to properly seat the flat head flush with the surface. De-energize or shut off all relevant systems before disassembling any panel or enclosure for fastener replacement. Avoid cross-threading by starting the screw by hand before applying torque.
