Value Collection HC1X05040-100BX M5 Hex Cap Screw 18-8 Ss Din 931

Product Description

The VALUE COLLECTION HC1X05040-100BX is a metric hex head cap screw designed for general-purpose fastening in mechanical, industrial, and trade applications. Sized at M5 x 0.80 thread pitch with a 40 mm length under the head, this screw is partially threaded per DIN 931, the widely recognized standard for hex head bolts with reduced thread length. Manufactured from 18-8 austenitic stainless steel, also designated Grade A2, the fastener offers good corrosion resistance and is well suited for use in wet, outdoor, or chemically active environments. The 8 mm hex drive allows installation with standard metric wrenches or sockets. This SKU is sold in a minimum order quantity of 100 pieces.

This fastener is appropriate for use in HVAC equipment assembly, plumbing fixture mounting, electrical enclosure fabrication, pool equipment installation, and general mechanical assemblies where metric hardware and corrosion resistance are required. The partial thread shank provides a bearing surface for clamping applications where full thread engagement throughout the grip length is not desired. The M5 x 0.80 thread form is a standard metric coarse pitch, compatible with M5 hex nuts, flange nuts, and threaded inserts following ISO metric specifications.

Installation Notes

Install using an 8 mm metric wrench, combination wrench, or socket driver. Verify that the receiving thread is clean and free of debris before installation. When fastening into dissimilar metals such as aluminum, use appropriate anti-galling compound to prevent thread seizing. Always confirm the correct torque specification from the equipment manufacturer or applicable mechanical standard before final tightening.
