Value Collection A410150 Hex Socket Cap Screw M3x0.5 316 Ss

Product Description

The VALUE COLLECTION A410150 is a fully threaded hex socket cap screw in metric M3 x 0.5 thread size with a 4 mm length under head. Manufactured from 316 austenitic stainless steel with a bright, uncoated finish, this fastener meets DIN 912 dimensional standards. The internal hex drive requires an appropriately sized hex key or Allen wrench for installation. Grade A4 stainless steel construction provides strong corrosion resistance, making this screw well suited for demanding or moisture-exposed environments. Each package contains 50 pieces.

This fastener is used across a wide range of light mechanical assemblies, electrical enclosures, HVAC equipment panels, plumbing fixture components, and general industrial applications where a compact, corrosion-resistant cap screw is required. The M3 x 0.5 thread profile and 4 mm under-head length are commonly specified in OEM equipment assemblies, instrumentation, and control panel fabrication. Electricians, HVAC technicians, plumbers, and mechanical contractors all encounter this screw size when servicing or assembling equipment with metric fastener specifications.

• Sold in a pack of 50 pieces

Compatibility

Designed as a direct-fit metric hex socket cap screw for any application specifying an M3 x 0.5 DIN 912 fastener in stainless steel.

Installation Notes

Installation requires a correctly sized metric hex key or hex bit driver; use of an improperly sized driver can round the socket and damage the fastener head. De-energize and lock out any electrical equipment before fastening components inside panels or enclosures in accordance with applicable NFPA 70E or local electrical code requirements. When installing stainless steel fasteners into stainless steel threads, apply an anti-seize compound to prevent galling. Inspect thread engagement and do not overtighten, as small-diameter stainless fasteners are susceptible to thread stripping if torque is excessive.
