Value Collection 643005PR M5x0.80x30mm Hex Cap Screw

Product Description

The VALUE COLLECTION 643005PR is a metric hex head cap screw manufactured from Grade 8.8 steel with a bright, uncoated finish. It carries an M5 x 0.80 thread and measures 30 mm under the head with full threading along its entire shank. The 8 mm hex drive size is compatible with standard metric wrenches and sockets. Grade 8.8 designates a medium-high strength carbon steel fastener suitable for general mechanical assemblies, light structural applications, and equipment maintenance. This screw conforms to DIN 933 and ISO 4017 standards, making it appropriate for applications requiring documented dimensional and mechanical compliance.

This fastener is used across a broad range of trade and industrial applications including HVAC equipment assembly, electrical enclosure mounting, plumbing fixture installation, and general mechanical repairs. The fully threaded shank is well suited for clamping through thin materials or threading into blind holes where engagement length is limited. It is commonly installed by HVAC technicians, industrial mechanics, and service professionals working on equipment with metric fastener specifications.

Compatibility

Designed as a standard metric replacement or stock fastener for any application requiring an M5 x 0.80 x 30 mm fully threaded hex head cap screw per DIN 933 or ISO 4017.

Installation Notes

Installation is performed with a standard 8 mm metric wrench, socket, or hex driver. Verify thread engagement depth and mating thread condition before installation. Do not exceed the rated mechanical properties of the Grade 8.8 designation by substituting this fastener in high-cycle fatigue or safety-critical structural joints without engineering review. Fastener selection and torque requirements should follow applicable equipment service documentation or recognized standards such as those published by ASME or ISO.
