Value Collection A410046 Hex Head Cap Screw M8 X 1.25

Product Description

The VALUE COLLECTION A410046 is a metric hex head cap screw designed for applications requiring corrosion-resistant fastening. Manufactured from Grade 316 austenitic stainless steel (Grade A4), this fully threaded fastener measures M8 x 1.25 thread size with a 16 mm length under head. It carries a 13 mm hex drive and conforms to DIN 933 standards. This screw is suited for use in marine, chemical, food processing, and outdoor environments where standard carbon steel fasteners would corrode. Installation is performed by machinists, pipefitters, millwrights, and general trade mechanics using standard metric tooling.

This fastener is appropriate for metric-threaded assemblies in both light and heavy industrial settings. Its fully threaded shank provides maximum thread engagement in shallow through-hole and tapped applications. The uncoated finish retains the natural surface properties of 316 stainless steel, which resists chlorides and oxidizing acids better than 304-series alloys. Typical applications include equipment mounting, structural bracketing, pump and valve assembly, and any bolted connection exposed to moisture, salt spray, or mild chemical environments. Each package contains 25 pieces.

Key Features

• Grade 316 austenitic stainless steel (Grade A4) for superior corrosion resistance in chloride-rich environments
• Fully threaded shank per DIN 933 for maximum thread engagement
• M8 x 1.25 metric thread — standard coarse pitch
• 16 mm length under head suits shallow through-hole and tapped assemblies
• 13 mm hex drive compatible with standard metric hex tooling
• Uncoated finish — no coating degradation risk in submerged or high-humidity service

Compatibility

Designed for use in any M8 x 1.25 metric-threaded application requiring a DIN 933 hex head cap screw in Grade 316 stainless steel.

Installation Notes

Install using a 13 mm wrench or socket. Ensure the mating threaded hole or nut is also stainless steel or a compatible alloy to prevent galvanic corrosion. Apply an appropriate anti-seize compound when fastening into stainless threads to reduce the risk of galling. Power down or de-energize any equipment before accessing fastened assemblies on live machinery.
