Value Collection 644058PR Hex Head Cap Screw M8 X 1.25

Product Description

The VALUE COLLECTION 644058PR is a metric hex head cap screw designed for general-purpose fastening applications requiring a strong, reliable threaded connection. Manufactured from Grade 8.8 steel with a bright, uncoated finish, this screw features an M8 x 1.25 thread profile and a 70 mm length under head. The 13 mm hex drive accommodates standard hex sockets and wrenches. Partial threading along the shank follows DIN 931 and ISO 4014 standards, making it a well-recognized fastener spec in mechanical assemblies, equipment fabrication, and maintenance work. Tradespeople, maintenance technicians, and fabricators handling metric hardware installations will find this a standard, interchangeable fastener for a wide range of structural and mechanical connections.

This fastener is suited for use in metric-fastened assemblies found in industrial machinery, HVAC equipment frames, plumbing equipment supports, electrical enclosures, and general mechanical structures. The partially threaded shank is appropriate where a grip length is needed between mating components before the threaded section engages the nut or tapped hole. It conforms to DIN 931 and ISO 4014 dimensional standards, which are widely specified in European-origin and metric equipment. This item is sold individually, with a minimum order quantity of 100 pieces per order.

Installation Notes

Installation is performed by maintenance technicians, millwrights, or trade professionals working with metric hardware. Always de-energize or shut down the equipment being serviced before fastener installation or removal. Use a calibrated torque wrench and follow the torque specifications listed in the equipment manufacturer's service documentation for Grade 8.8 M8 fasteners. Do not substitute a coated or different-grade fastener where a specific grade or finish is called out in engineering drawings.
