Value Collection FHS1XX0516-050BX M5x0.8 Flat Socket Cap Screw

Product Description

The VALUE COLLECTION FHS1XX0516-050BX is a metric flat socket cap screw designed for applications requiring a flush or countersunk fastening profile. The 90-degree flat head seats flush with the mating surface when installed in a properly countersunk hole, eliminating protrusion. Driven by a 3.00 mm hex socket (Allen key), it provides reliable torque transfer in tight spaces. Manufactured from 316 austenitic stainless steel to Grade A4, it delivers strong corrosion resistance in wet, marine, chemical, and food-processing environments. The M5x0.8 thread is fully threaded along its 16.00 mm overall length, conforming to DIN 7991. This fastener is sold in a minimum order quantity of 50 pieces per package.

This screw is suited for industrial, marine, food-service, and general mechanical assembly applications where a flush fastener profile is required and corrosion resistance is a priority. The fully threaded shank provides maximum thread engagement across the full grip length, making it appropriate for thin material assemblies or through-bolt configurations. It is commonly installed by machinists, millwrights, maintenance technicians, and fabricators working with stainless steel structures, enclosures, pumps, and marine hardware.

Key Features

• 90-degree flat head profile seats flush in countersunk holes to eliminate surface protrusion

• M5x0.8 metric thread fully threaded over 16.00 mm overall length per DIN 7991
• 3.00 mm hex socket drive for precise torque application in confined clearances
• Sold in packs of 50 to support production and maintenance stocking requirements

Compatibility

Designed as an OEM-style and aftermarket replacement flat socket cap screw for metric-threaded assemblies requiring a DIN 7991 M5x0.8 countersunk fastener in 316 stainless steel.

Installation Notes

Installation requires a 3.00 mm hex socket key or driver bit. The mating material must be pre-drilled and countersunk to a 90-degree angle to achieve proper head seating. Verify thread engagement depth meets design requirements before final torque. When installing in stainless-to-stainless assemblies, apply an anti-galling compound to prevent thread seizure during installation.
