Value Collection FHS1X1645 Flat Socket Cap Screw M16x2

Product Description

The VALUE COLLECTION FHS1X1645 is a metric flat socket cap screw designed for flush or countersunk fastening applications in machinery, fixtures, and structural assemblies. Built from 18-8 austenitic stainless steel at Material Grade A2, it delivers solid corrosion resistance and mechanical strength without surface coating. The M16x2 thread and 45 mm overall length make it a standard choice for medium-to-heavy fastening tasks. A 10 mm hex socket drive accepts an Allen key or hex bit for controlled tightening in recessed or tight-clearance positions. The 90-degree flat head sits flush or below the surface when installed in a properly countersunk hole.

This flat socket cap screw is suited for industrial, commercial, and mechanical applications where a flush fastener profile is required. Common install scenarios include machinery frames, structural brackets, panels, and equipment assemblies that require a low-profile head. The partial threading design concentrates the thread engagement in the correct zone and allows for shoulder-type clamping. Licensed mechanics, millwrights, pipefitters, and maintenance technicians working in corrosive or wet environments frequently specify A2 stainless hardware to meet service life requirements.

Key Features

• 18-8 austenitic stainless steel construction at A2 material grade for corrosion resistance
• 90-degree flat head profile seats flush in countersunk holes for a clean, low-profile finish
• 10 mm hex socket drive for use with Allen keys or hex-socket power tools
• Partially threaded shank allows shoulder clamping and proper load distribution
• Thread Fit Class 6G per metric standards for consistent, reliable engagement
• Conforms to DIN 7991 fastener standard

Compatibility

Designed as an OEM-style metric flat socket cap screw for use in any application requiring an M16x2 thread, 45 mm overall length, and a 90-degree countersunk flat head per DIN 7991.

Installation Notes

Installation requires a properly sized countersunk hole to fully seat the 90-degree flat head flush with the mating surface. Use a calibrated 10 mm hex key or hex-socket bit driver and torque to the value specified in the assembly drawing or engineering specification for A2 stainless M16 fasteners. Avoid using impact drivers without a torque-limiting clutch, as over-torquing stainless fasteners can cause galling or thread seizure. Apply an anti-seize compound rated for stainless steel if the assembly may require future disassembly in corrosive environments.
