Value Collection FHS1X1660 Flat Socket Cap Screw M16x2

Product Description

The VALUE COLLECTION FHS1X1660 is a metric flat socket cap screw designed for flush or countersunk fastening applications requiring corrosion-resistant hardware. Built to DIN 7991 standards, it features a 90-degree flat head with a 10 mm hex socket drive and a partially threaded shank. The thread specification is M16x2, with an overall length of 60 mm. Manufactured from 18-8 austenitic stainless steel meeting Grade A2 requirements, this fastener delivers reliable performance in wet, chemical-exposure, or outdoor environments where carbon steel hardware would corrode. Installers and tradespeople working in plumbing, mechanical, or structural applications select this screw when a low-profile head seating flush with the work surface is required.

This flat socket cap screw is suited for mechanical assemblies, equipment mounting, and structural connections where a countersunk seat is machined or stamped into the mating material. The M16x2 thread size and partial threading make it appropriate for through-bolt and tapped-hole configurations in medium-to-heavy fastening scenarios. Its stainless steel construction makes it a practical choice for marine, food-service, chemical processing, and outdoor industrial environments. The hex socket drive allows torque application with a standard Allen key or hex bit driver, making installation accessible in tight or recessed clearances.

Compatibility

Designed as a DIN 7991-compliant metric flat socket cap screw for use in any application calling for an M16x2 countersunk hex socket fastener in stainless steel.

Installation Notes

Installation requires a 10 mm hex key or Allen bit driver rated for the applied torque. Ensure the mating material has a properly machined or stamped 90-degree countersink to match the flat head angle before installing. Power down or de-energize any equipment before fastening components in electrical or mechanical enclosures. Avoid mixing stainless steel fasteners with dissimilar metals in submerged or high-humidity environments to minimize galvanic corrosion risk.
