Value Collection 535058PR M5x0.8 Button Socket Cap Screw

Product Description

The VALUE COLLECTION 535058PR is a fully threaded button socket cap screw designed for precision fastening applications where a low-profile head and high clamping strength are required. Built from alloy steel with a black oxide coating, it meets ISO 7380 and ANSI/ASME B18.3.4M standards. The M5x0.8 thread pitch and 25mm length under head make it well suited for medium-duty assemblies. A 3mm hex socket drive and grade 12.9 material classification provide the torque capacity needed in demanding mechanical and industrial installations. Hardness is rated at 38 to 43 HRC.

This screw is commonly used in machine assemblies, jigs, fixtures, tooling, and equipment panels where a button-head profile reduces snagging and a clean surface appearance is preferred. The black oxide finish offers mild corrosion resistance and reduces light reflection, making it a practical choice in both shop and field settings. It is installed by mechanical assemblers, maintenance technicians, and machine builders working with metric fastener specifications.

Key Features

Compatibility

Designed as an OEM-style metric fastener for use in applications requiring an M5x0.8 fully threaded button socket cap screw per ISO 7380 and ANSI/ASME B18.3.4M standards.

Installation Notes

Installation requires a 3mm hex key or hex socket driver rated for the torque demands of a grade 12.9 fastener. Always verify thread fit class compatibility with the mating component before assembly. Follow applicable ANSI or ISO torque guidance for M5 class 12.9 fasteners to avoid thread damage or fastener failure. Minimum order quantity is 100 units.
