Value Collection A210131 M2 Hex Socket Cap Screw 100pk

Product Description

The VALUE COLLECTION A210131 is a fully threaded hex socket cap screw sized M2 x 0.40 metric with an 8 mm length under head. Manufactured from 18-8 austenitic stainless steel (Material Grade A2) and left with a bright, uncoated finish, this fastener meets DIN 912 standards. The internal hex drive requires an appropriate hex key or Allen wrench for installation. It is sold in a package of 100 pieces, making it practical for production assembly, maintenance kits, and repair work requiring small-diameter metric fasteners.

This screw is suited for light-duty mechanical assemblies, electronic enclosures, instrumentation panels, and precision equipment where a small metric fastener with corrosion resistance is needed. The M2 thread size and 8 mm under-head length make it a common choice in applications where space is tight and material thickness is minimal. Tradespeople and technicians working in HVAC controls, electrical panels, or small equipment assemblies will find this fastener appropriate for securing lightweight components.

Key Features

• DIN 912 standard hex socket cap screw for consistent dimensional compliance
• 18-8 austenitic stainless steel, Material Grade A2, for corrosion resistance
• Fully threaded along the entire shank length for maximum thread engagement
• Bright, uncoated finish — no coating thickness to account for in tight tolerances
• Internal hex drive for use with standard hex keys or Allen wrenches
• Sold in a 100-piece package for stocking and repetitive assembly tasks

Compatibility

Designed as a general-purpose M2 x 0.40 metric hex socket cap screw conforming to DIN 912, suitable for use in any application requiring that thread specification and an 8 mm under-head length.

Installation Notes

Installation requires a correctly sized metric hex key to avoid cam-out and fastener damage. Ensure mating threads are clean and free of debris before driving. Apply appropriate torque for M2 stainless fasteners per the assembly specification of the equipment being serviced — do not overtighten, as small-diameter stainless screws are susceptible to galling. Stainless-to-stainless thread engagement may benefit from anti-seize compound to prevent galling during installation.
