Value Collection MHCS08C0409MBPKG M8x1.25 Hex Cap Screw 40mm 10pk

Product Description

The VALUE COLLECTION MHCS08C0409MBPKG is a metric hex head cap screw engineered for high-strength fastening applications. Manufactured from grade 10.9 alloy steel with a zinc-blue trivalent chromate finish, it delivers reliable clamping force in demanding mechanical and structural assemblies. The M8x1.25 thread is partially threaded per DIN 931 and ISO 4014 standards, with a 40 mm length under head. The trivalent chromate coating provides corrosion resistance while remaining RoHS and REACH compliant. This package contains 10 screws. Installation requires a 5.45 mm hex key or a standard metric hex socket driver.

These cap screws are suited for general mechanical assemblies, equipment fabrication, machinery maintenance, and structural connections where metric fasteners are specified. Partially threaded shanks make them well-suited for applications requiring a clamp zone between mating surfaces. Typical users include industrial maintenance technicians, equipment builders, and trade professionals working on HVAC equipment frames, pump assemblies, or similar metal structures that call for a high-strength metric fastener conforming to DIN 931 or ISO 4014.

Installation Notes

Installation is performed by qualified mechanical or maintenance technicians using a calibrated torque wrench and the appropriate 5.45 mm hex bit or metric socket. De-energize and lock out all equipment before replacing fasteners in powered assemblies. Follow applicable torque specifications for grade 10.9 M8 fasteners as defined by the equipment manufacturer or relevant industry standards. Do not mix metric and inch-series fasteners in the same joint.
