Value Collection FHS1XX0512-050BX M5x0.8 Flat Cap Screw

Product Description

The VALUE COLLECTION FHS1XX0512-050BX is a metric flat socket cap screw designed for flush or countersunk fastening applications. It features a 90-degree flat head with a 3.00 mm hex socket drive and is fully threaded along its 12.00 mm overall length with an M5x0.8 thread pitch. Manufactured from 316 austenitic stainless steel to Grade A4, this screw provides strong corrosion resistance in wet, marine, and chemically exposed environments. It conforms to DIN 7991. Typical installers include machinists, millwrights, maintenance technicians, plumbers, and HVAC service professionals who require a low-profile fastener that sits flush with or below the mating surface.

This flat socket cap screw is suited for general industrial and mechanical assembly where a countersunk, flush-mount fastener is required. The 316 stainless steel construction makes it appropriate for use in marine equipment, food-processing machinery, pool and water treatment equipment, and outdoor or high-humidity installations. The hex socket drive accommodates a standard 3.00 mm Allen key or hex bit, which is commonly available in trade tool sets. This item is sold in a minimum order quantity of 50 pieces per order.

Compatibility

Designed as an OEM-style or replacement flat socket cap screw for metric-threaded assemblies requiring a DIN 7991 M5x0.8 fastener with a countersunk 90-degree flat head profile.

Installation Notes

Installation is performed using a 3.00 mm hex key or hex socket driver. Ensure the mating surface is properly countersunk to the correct 90-degree angle before driving the fastener to avoid head deformation. Do not overtorque stainless steel fasteners, as galling can occur; applying an appropriate anti-seize compound is a common trade practice when assembling stainless steel hardware. Verify thread fit and surface preparation before final assembly.
