Value Collection FHS1X1650 Flat Socket Cap Screw M16x2

Product Description

The VALUE COLLECTION FHS1X1650 is a metric flat socket cap screw designed for flush or countersunk fastening applications where a low-profile head is required. It features a 90-degree flat head with a 10 mm hex socket drive and is manufactured from 18-8 austenitic stainless steel, also classified as Grade A2, providing reliable corrosion resistance in wet, chemical, or outdoor environments. The M16x2 thread size with a 50 mm overall length and partial threading makes it well-suited for through-bolting into tapped holes where thread engagement is needed only at the bearing end. Fabricators, millwrights, pipefitters, and maintenance technicians commonly install this fastener in assemblies requiring a smooth, flush surface finish.

This screw is appropriate for use in structural and mechanical assemblies across industrial, marine, plumbing, and HVAC applications where stainless steel fasteners are specified for corrosion resistance. The countersunk head seats flush with the mating surface, eliminating protrusions that could interfere with clearances or moving components. Its metric thread standard and DIN 7991 fastener standard make it a direct fit for equipment designed to metric specifications commonly found in commercial and industrial systems.

Key Features

• 90-degree flat countersunk head for flush installation in countersunk holes
• 10 mm hex socket drive for high-torque seating with a standard hex key or Allen driver
• M16x2 metric thread with 50 mm overall length, partially threaded
• 18-8 austenitic stainless steel (Grade A2) for corrosion resistance in demanding environments
• Conforms to DIN 7991 fastener standard for metric compatibility

Compatibility

Designed as a DIN 7991 metric flat socket cap screw in M16x2 thread size, suitable for countersunk fastening applications in equipment and assemblies that specify 18-8 or Grade A2 stainless steel hardware with metric threading.

Installation Notes

Installation is performed with a 10 mm hex key or socket driver; ensure the mating hole is properly countersunk to 90 degrees to achieve full head seating. Verify that the tapped receiving hole meets the M16x2 thread specification before installation to avoid cross-threading. As with all stainless fasteners, apply an appropriate anti-seize compound when threading into stainless or aluminum to prevent galling. Torque to the value specified by the equipment manufacturer or applicable engineering standard for the assembly.
