Value Collection A410166 M4 Hex Socket Cap Screw 25-pack

Product Description

The VALUE COLLECTION A410166 is a fully threaded hex socket cap screw in M4 x 0.70 metric thread, sized at 8 mm length under head. Manufactured from 316 stainless steel to austenitic Grade A4 standards, this fastener offers strong corrosion resistance in wet, chemical, and marine environments. Drive type is hex socket (Allen key), conforming to DIN 912. This package contains 25 screws. Installation is performed by maintenance technicians, millwrights, and mechanical contractors working on equipment assemblies, enclosures, and fixtures that require metric fasteners with high corrosion resistance.

This screw is suited for light-duty mechanical assemblies, electrical enclosure panels, HVAC equipment brackets, and plumbing fixture mounting where metric thread engagement and stainless steel durability are required. The M4 x 0.70 thread pitch and 8 mm under-head length make it a common fit for thin-panel and frame assemblies across residential and commercial service applications. Sold in a 25-piece package to support typical service quantities.

Key Features

• 316 stainless steel construction with austenitic Grade A4 rating for superior corrosion resistance
• Fully threaded shank for maximum thread engagement across the entire fastener length
• Hex socket drive (Allen key) for torque-efficient installation in tight spaces
• Conforms to DIN 912 fastener standard for consistent dimensional accuracy
• Bright uncoated finish — no added coating that could interfere with precise thread fit
• Packaged in quantities of 25 to support standard service and repair jobs

Compatibility

Designed as a standard DIN 912 metric hex socket cap screw for use in any application requiring M4 x 0.70 thread pitch with an 8 mm under-head length in stainless steel.

Installation Notes

Installation requires a metric hex key or Allen driver sized for M4 socket cap screws. Power down or de-energize any associated equipment before fastener service on electrical or mechanical assemblies. Do not use impact drivers without a torque-limiting attachment, as over-torquing stainless steel fasteners can cause galling of the threads. Verify thread engagement and mating material compatibility before final assembly.
