Value Collection FHS1X1690-010BX M16x2 Flat Socket Cap Screw

Product Description

The VALUE COLLECTION FHS1X1690-010BX is a metric flat socket cap screw designed for flush or countersunk fastening applications. Manufactured from 18-8 austenitic stainless steel to Material Grade A2, it provides corrosion resistance suitable for general industrial, marine-adjacent, and food-adjacent environments. The screw measures 90.00 mm in overall length with an M16x2 thread size and a 10.00 mm hex socket drive. The 90-degree flat head seats flush with or below the surface of the mating material, making it the correct choice where a protruding head would interfere with assembly clearances or aesthetics. Threading is partial, with a 38.00 mm thread length, conforming to DIN 7991 and Thread Fit Class 6G.

This fastener is used across mechanical assembly, structural fabrication, equipment mounting, and maintenance repair operations where a flush-mount metric fastener is required. The M16 diameter and partial threading make it well suited for through-bolting into tapped holes in metal frames, machinery housings, and heavy-duty fixtures. Trades that commonly spec this fastener include millwrights, industrial mechanics, and maintenance technicians working with metric-standard equipment.

Key Features

• 90-degree flat head for flush or countersunk seating
• 10.00 mm hex socket drive for high-torque installation
• 18-8 austenitic stainless steel, Material Grade A2 for corrosion resistance
• Partial threading with 38.00 mm thread length on M16x2 pitch
• Conforms to DIN 7991 fastener standard, Thread Fit Class 6G
• Plain finish with no coating — ready for use or field treatment

Compatibility

Designed as a DIN 7991-compliant M16x2 flat socket cap screw suitable for use in metric-threaded assemblies requiring a 90-degree countersunk head profile.

Installation Notes

Installation requires a 10.00 mm hex key or socket driver rated for the torque demands of an M16 fastener. The countersunk mating hole should be machined or drilled to match the 90-degree included angle before installation. Power down or de-energize any equipment before fastener service on live assemblies. Thread Fit Class 6G specifies a standard clearance tolerance — verify mating nut or tapped hole class before assembly in precision applications.
