Value Collection A410151 M3x0.50 Hex Socket Cap Screw 50pk

Product Description

The VALUE COLLECTION A410151 is a fully threaded hex socket cap screw in M3 x 0.50 metric thread with a 5 mm length under head. Manufactured from 316 stainless steel (Austenitic Grade A4), this fastener offers excellent corrosion resistance and is well suited for demanding environments where moisture or chemical exposure is a concern. The hex socket drive accepts a standard Allen key or hex bit, allowing installation in tight clearances where a conventional wrench cannot reach. Sold in a pack of 50, this screw is appropriate for mechanical assembly, fabrication, and equipment maintenance work performed by machinists, millwrights, HVAC technicians, and other trade professionals.

This fastener is designed for general metric fastening applications where a socket-drive cap screw is required. Its fully threaded shank and M3 x 0.50 pitch make it suitable for through-hole and tapped-hole assemblies in light mechanical, HVAC equipment, electrical enclosure, and instrumentation applications. The Grade A4 stainless steel construction is preferred in marine, food-service, and outdoor installations where standard carbon steel fasteners would be prone to rust or galvanic corrosion.

Key Features

• M3 x 0.50 metric thread, fully threaded shank for maximum grip in short-depth tapped holes
• 5 mm length under head — compact profile for shallow assemblies
• 316 stainless steel, Austenitic Grade A4 — superior corrosion resistance versus standard 18-8 grades
• Hex socket (Allen) drive for installation in confined spaces
• Bright/uncoated finish — no coating variability affecting thread tolerance
• Conforms to DIN 912 fastener standard
• Pack of 50 — supports production runs and maintenance stock replenishment

Compatibility

Designed for use in any application requiring a DIN 912 metric hex socket cap screw with M3 x 0.50 thread pitch and a 5 mm under-head length in 316 stainless steel.

Installation Notes

Install using a correctly sized metric hex key or hex bit driver to avoid rounding the socket drive. Verify that the mating tapped hole is clean, properly dimensioned for M3 x 0.50 thread, and free of debris before driving the screw. When fastening into dissimilar metals, apply an appropriate anti-galling compound to reduce the risk of thread seizure common with stainless fasteners. Follow applicable mechanical or equipment manufacturer torque guidelines based on the specific assembly.
