Value Collection HC1008045-100BX M8 Hex Cap Screw Din 931

Product Description

The VALUE COLLECTION HC1008045-100BX is a partially threaded hex head cap screw engineered for metric fastening applications that demand high tensile strength. Built to Grade 10.9 steel, this fastener delivers a proof load and yield strength well above standard hardware grades, making it suitable for structural and mechanical assemblies where joint integrity is critical. The M8 x 1.25 thread pitch and 45 mm length under head are manufactured to DIN 931 standards. A black oxide finish provides light corrosion resistance and a uniform appearance. Licensed tradespeople, millwrights, and industrial mechanics routinely specify Grade 10.9 hardware for heavy-duty bolted connections.

This screw is suited for metal-to-metal fastening in machinery, equipment frames, automotive components, and industrial fabrication. The partial threading leaves a smooth shank section near the head, which provides shear resistance and accurate bolt positioning in close-tolerance through-holes. Applications include general mechanical assembly, maintenance repair, and OEM production work requiring metric DIN hardware. The 13 mm hex drive is compatible with standard metric wrenches and sockets. Sold in a minimum order quantity of 100 pieces per order, making this fastener appropriate for production line restocking and bulk service truck inventory.

Key Features

• Grade 10.9 alloy steel construction for high tensile and proof load strength
• Partially threaded shank per DIN 931 for shear resistance and close-tolerance fit
• M8 x 1.25 metric thread size with 45 mm length under head
• Black oxide finish for light corrosion resistance and reduced light reflection
• 13 mm hex drive compatible with standard metric wrenches and sockets
• DIN 931 standard compliance for dimensional consistency and interchangeability

Compatibility

Designed as a standard DIN 931 metric hex head cap screw for use in any M8 x 1.25 threaded application requiring a partially threaded, Grade 10.9 fastener.

Installation Notes

Installation should be performed by a qualified mechanic, millwright, or assembler familiar with metric fastener torque specifications for Grade 10.9 hardware. Always verify thread engagement depth and hole condition before installation. Do not substitute Grade 10.9 fasteners in joints designed for lower-grade hardware without engineering review, and do not mix metric and unified thread standards. Torque to the value specified by the equipment manufacturer or applicable engineering standard for M8 Grade 10.9 fasteners.
