Value Collection 4506 Hex Head Cap Screw M8 X 1.25 40mm 50pk

Product Description

The Value Collection 4506 is a metric hex head cap screw designed for general fastening applications where consistent clamping strength and corrosion resistance are required. Sized at M8 x 1.25 with a 40 mm length under head, this screw is manufactured from Grade 8.8 steel with a zinc-plated finish that provides moderate corrosion protection. The partial threading configuration concentrates clamping force on the bearing surface, making it suitable for bolted joint assemblies in light industrial, mechanical, and fabrication settings. The 13 mm hex drive is compatible with standard metric wrenches and sockets. Sold in packs of 50, it suits both single-job use and shop-stock replenishment.

This fastener is appropriate for use in mechanical assemblies, equipment fabrication, HVAC equipment mounting, and general structural bolting where metric thread standards are specified. The JIS B1180-7 standard designation makes it suitable for applications requiring Japanese Industrial Standard compliance. It is commonly used by maintenance technicians, fabricators, and equipment assemblers working with metric-dimensioned components and frames.

Installation Notes

Installation is performed with a 13 mm metric wrench or socket driver. Always verify thread engagement and hole depth before driving to prevent cross-threading or bottoming out. Torque to the value specified by the equipment manufacturer or applicable engineering standard for Grade 8.8 fasteners. Do not substitute for applications requiring a higher grade fastener without confirming load and safety requirements.
