Value Collection C90399 M8 X 1.25 75mm Hex Cap Screw

Product Description

The Value Collection C90399 is a metric hex head cap screw designed for high-strength fastening applications in mechanical assemblies, industrial equipment, and structural connections. Sized M8 x 1.25 with a 75 mm length under head and fully threaded shank, this fastener is manufactured from Grade 10.9 steel with a zinc-plated finish for corrosion resistance. The 13 mm hex drive accepts standard metric wrenches and sockets. Conforming to ASME B18.0.3.1M, this screw meets recognized dimensional and performance standards for metric fasteners used in professional trade and industrial settings.

This cap screw is suited for use in machinery assembly, equipment mounting, and structural fabrication where a high-strength metric fastener is required. The fully threaded shank provides consistent clamping force along the full engaged length, making it appropriate for through-bolt applications or threaded-insert installations in steel, aluminum, and other substrates. Sold in packages of 10, this fastener is appropriate for maintenance, repair, and production environments.

Installation Notes

Installation should be performed by a qualified mechanic or millwright using calibrated metric hand tools or power tools set to appropriate torque specifications for the application and joint material. Always consult the equipment manufacturer's torque table for Grade 10.9 M8 fasteners before final tightening. Inspect threads in the mating component for damage or contamination before installation. Do not reuse fasteners that show signs of thread deformation, corrosion, or mechanical damage.
