Value Collection 44057 M8x1.25x40mm Hex Cap Screw Zinc

Product Description

The VALUE COLLECTION 44057 is a metric hex head cap screw designed for general mechanical fastening applications requiring a high-strength, partially threaded fastener. Built to Grade 12.9 steel with a zinc-plated finish, this screw measures M8 x 1.25 thread pitch and 40 mm in length under the head. The 13 mm hex drive allows installation with standard hex wrenches or sockets. Zinc plating provides corrosion resistance in light-duty environmental exposure. This fastener is sold in packages of 50 and meets ISO 12.9 standards, making it appropriate for precision mechanical assemblies, machinery, and structural connections where dimensional consistency and material strength are required.

This screw is suited for metric fastening applications in industrial, manufacturing, and mechanical maintenance environments. Partial threading provides a smooth shank section for applications where the fastener must pass through a clearance hole before engaging a threaded bore. Typical installers include maintenance technicians, machinists, and mechanical assemblers working on equipment where M8 metric fasteners are specified. The zinc finish is appropriate for indoor and light outdoor use where mild corrosion resistance is needed.

Key Features

• Grade 12.9 steel construction for high tensile strength
• M8 x 1.25 mm thread pitch conforming to metric thread standards
• 40 mm length under head for precise fitment in specified clearance depths
• Partially threaded shank for clearance-hole pass-through applications
• Zinc-plated finish for corrosion resistance in light-duty service
• 13 mm hex drive compatible with standard metric wrenches and sockets

Compatibility

Designed as a standard ISO metric replacement or stock fastener for applications specifying an M8 x 1.25 x 40 mm partially threaded hex head cap screw in Grade 12.9 steel.

Installation Notes

Installation should be performed by a qualified technician or machinist familiar with metric fastener torque requirements. Always consult the equipment manufacturer's torque specification table for M8 Grade 12.9 fasteners before tightening. Ensure the mating threaded bore is clean and free of debris before installation. Do not mix metric and imperial fasteners in the same assembly.
