Value Collection 643956PR M7 Hex Head Cap Screw Grade 8.8

Product Description

The VALUE COLLECTION 643956PR is a metric hex head cap screw designed for general-purpose mechanical fastening applications. Manufactured from Grade 8.8 steel with a bright, uncoated finish, this fully threaded fastener meets DIN 933 and ISO 4017 standards. The M7 x 1.00 thread pitch and 16 mm length under head make it a precise fit for metric-spec assemblies in industrial, automotive, and equipment manufacturing environments. At 0.017 pounds per piece, it is a lightweight fastener suited for moderate-load structural connections. Installation requires a standard 7 mm hex wrench or socket.

This screw is appropriate for use in metric-dimensioned assemblies across a broad range of industries including machine building, automotive repair, general fabrication, and light structural applications. It is commonly installed by machinists, millwrights, and mechanical technicians working to metric fastener specifications. The fully threaded shank engages the full length of the mating thread, making it well suited for through-bolt and close-tolerance clamping applications where consistent thread engagement is required.

Key Features

• Grade 8.8 steel construction provides a good balance of tensile strength and ductility for general metric fastening
• Fully threaded shank per DIN 933 and ISO 4017 standards ensures maximum thread engagement
• M7 x 1.00 thread specification for precise fit in metric-dimensioned components
• Bright, uncoated finish suitable for indoor and dry-environment use
• 7 mm hex drive compatible with standard metric wrenches and sockets
• 16 mm length under head for controlled clamp length in typical assembly applications

Compatibility

Designed as an OEM-style metric fastener replacement or new-installation screw for any assembly calling for an M7 x 1.00 x 16 mm fully threaded hex head cap screw per DIN 933 or ISO 4017.

Installation Notes

Installation is typically performed by machinists, maintenance technicians, or mechanical assemblers using a standard 7 mm hex wrench or socket drive. Ensure mating threaded holes are clean and free of debris before installation. Apply thread lubricant or threadlocker only where specified by the equipment manufacturer. Fastener should be tightened to the torque value specified in the original equipment assembly documentation for Grade 8.8 metric hardware.
