Value Collection 644579PR M5 X 0.80 X 80 Mm Hex Cap Screw

Product Description

The VALUE COLLECTION 644579PR is a metric hex head cap screw designed for general fastening applications requiring a strong, reliable threaded connection. Built to Grade 8.8 steel, this screw delivers a tensile strength appropriate for medium- to high-load assemblies in industrial, mechanical, and equipment-maintenance settings. The partially threaded shank follows DIN 931 and ISO 4014 standards, making it a recognized specification part for engineers, machinists, and maintenance technicians working to metric tolerances. The uncoated bright finish means no additional coating thickness to account for in close-tolerance fits. Drive is via an 8 mm hex head.

This screw is suited for use in fabrication, machinery assembly, equipment repair, and maintenance environments where metric fasteners are specified. The M5 x 0.80 thread pitch and 80 mm length under head make it appropriate for through-bolt applications in panels, brackets, housings, and structural subassemblies. Technicians working on HVAC equipment, pumps, motors, and general mechanical assemblies will encounter this size frequently in OEM and field-repair contexts. The DIN 931 and ISO 4014 standards ensure dimensional interchangeability with other conforming metric fasteners.

Key Features

• Grade 8.8 steel construction for reliable medium- to high-load clamping performance
• Partially threaded shank per DIN 931 and ISO 4014 for precise dimensional conformance
• M5 x 0.80 mm thread pitch with 80 mm length under head
• 8 mm hex drive head for use with standard metric wrenches and sockets
• Bright uncoated finish maintains dimensional accuracy in close-tolerance applications
• UNSPSC Code 31161501 for streamlined procurement and catalog alignment

Compatibility

Designed as a standard metric replacement or maintenance fastener conforming to DIN 931 and ISO 4014 specifications, compatible with any application requiring an M5 x 0.80 partially threaded hex head cap screw.

Installation Notes

Installation is performed by machinists, maintenance technicians, or trade professionals using a standard metric socket or open-end wrench sized to the 8 mm hex head. Always ensure mating threads are clean and free of damage before installation. Do not exceed the torque rating appropriate for Grade 8.8 M5 fasteners as specified by the equipment manufacturer or applicable engineering standards. Minimum order quantity is 100 units; verify quantity requirements before ordering.
