Value Collection FHS1X16100-010BX Flat Socket Cap Screw M16x2

Product Description

The VALUE COLLECTION FHS1X16100-010BX is a flat socket cap screw machined from 18-8 austenitic Grade A2 stainless steel, designed for flush or countersunk fastening applications where corrosion resistance and a low-profile head are required. The screw features a 90-degree flat head driven by a 10 mm hex socket and is partially threaded along its 100 mm overall length with an M16x2 metric thread pitch. It meets the DIN 7991 fastener standard. Machinists, millwrights, and maintenance technicians use this fastener when a standard cap screw head would protrude above the mating surface.

This screw is suited for metal fabrication, machine assembly, and industrial maintenance tasks where a countersunk fastening point is needed. The metric M16x2 thread size and 100 mm length make it appropriate for medium-to-heavy structural and mechanical assemblies. The 18-8 stainless steel construction resists rust and mild chemical exposure, making it a practical choice for both indoor and outdoor applications in manufacturing, food processing, and marine-adjacent environments.

Key Features

• 90-degree flat head sits flush with or below the mating surface when properly countersunk
• 10 mm hex socket drive for use with standard hex keys or socket wrenches
• M16x2 metric thread pitch conforms to DIN 7991 fastener standard
• Partially threaded shank provides a bearing surface and reduces stress concentration
• 18-8 austenitic Grade A2 stainless steel offers good corrosion resistance without heat treatment
• 100 mm overall length accommodates moderate material stack depths

Compatibility

Designed as a DIN 7991-compliant metric flat socket cap screw suitable for M16x2 tapped holes in steel, aluminum, and similar structural materials requiring a flush countersunk fastener.

Installation Notes

Installation requires a properly sized 90-degree countersink in the through-hole material to achieve a flush seating surface. Use a calibrated 10 mm hex key or torque wrench socket insert and tighten to the torque specification called out in the assembly drawing or applicable fastener standard. Ensure threads are clean and free of debris before installation. Stainless steel fasteners are susceptible to galling — apply an appropriate anti-seize compound when threading into stainless or aluminum tapped holes.
