Value Collection FHS1XX1220-050BX M12x1.75 Flat Socket Cap Screw

Product Description

The VALUE COLLECTION FHS1XX1220-050BX is a flat socket cap screw manufactured from 316 austenitic stainless steel to Material Grade A4, conforming to DIN 7991. It features a 90-degree flat head driven by an 8 mm hex socket, making it suitable for flush or countersunk installations where a low-profile fastener is required. The screw is fully threaded with an M12x1.75 thread profile and a 6G thread fit class, providing consistent engagement across a wide range of tapped holes and nut configurations. Installers working in corrosive or marine-adjacent environments commonly specify 316 stainless for its enhanced resistance to chlorides and oxidizing media.

This fastener is appropriate for structural and mechanical assemblies that require a countersunk, flush-mount connection in stainless steel. The 90-degree flat head seats cleanly into standard countersunk holes, eliminating protrusion above the mating surface. Typical applications include marine hardware, food-processing equipment, chemical handling assemblies, and architectural metalwork where corrosion resistance and a clean surface profile are both priorities. The plain finish retains the natural 316 stainless steel surface without additional plating or coating.

Key Features

• 316 austenitic stainless steel construction, Material Grade A4 per DIN 7991
• 90-degree flat head with 8 mm hex socket drive for countersunk installations
• M12x1.75 metric thread, 6G thread fit class for standard tolerance engagement
• Fully threaded along entire shank length for maximum thread engagement flexibility
• Plain finish preserves base stainless steel corrosion resistance without added coating
• Metric thread standard suits international and metric-specified assemblies

Compatibility

Designed for use in standard M12x1.75 countersunk holes conforming to metric fastener specifications per DIN 7991, compatible with metric hex socket tooling requiring an 8 mm drive.

Installation Notes

Installation requires a calibrated 8 mm hex socket driver or Allen key; use of a torque wrench is recommended practice for structural fastener applications. Ensure the mating countersink angle matches 90 degrees before seating the fastener to prevent head deformation or incomplete seating. Power down and de-energize any electrically live assemblies before fastener service. Stainless steel fasteners are susceptible to galling during installation — applying an appropriate anti-seize compound rated for stainless steel is standard practice to prevent thread seizure.
