Value Collection 644573PR M5x0.80x50mm Hex Cap Screw

Product Description

The VALUE COLLECTION 644573PR is a metric hex head cap screw designed for general mechanical fastening in assemblies where dimensional accuracy and material consistency matter. The screw is M5 x 0.80 thread pitch with a 50 mm length under the head, partially threaded per DIN 931 and ISO 4014 standards. Constructed from Grade 8.8 steel with a bright, uncoated finish, it delivers reliable tensile strength for medium-duty bolted connections. The 8 mm hex drive is compatible with standard metric tooling. This fastener is sold individually with a minimum order quantity of 100 units, making it suited for shop stock, maintenance bins, or production line replenishment.

This screw is appropriate for use in machinery, equipment assembly, structural brackets, and general fabrication work requiring a metric-standard partially threaded hex bolt. The partial thread design allows the unthreaded shank to bear shear loads and align mating components before thread engagement. It is commonly specified by maintenance technicians, millwrights, machinists, and field service personnel working on metric-dimensioned equipment. The uncoated finish is typical for indoor or protected applications where corrosion exposure is minimal.

Compatibility

Designed as a standard metric replacement or stock fastener conforming to DIN 931 and ISO 4014 specifications for M5 x 0.80 partially threaded hex head cap screws.

Installation Notes

Installation is performed by machinists, maintenance technicians, or assemblers using standard metric hand tools or power drivers with an 8 mm hex socket or wrench. Always ensure mating threads are clean and free of debris before driving the fastener. Do not exceed the torque capacity appropriate for Grade 8.8 M5 fasteners as specified by the equipment manufacturer or applicable engineering standards. Inspect threads on both the fastener and the receiving component for damage before assembly.
