Value Collection MKBC05C020MBPKG M5x0.8 Button Cap Screw 50pk

Product Description

The VALUE COLLECTION MKBC05C020MBPKG is a button socket cap screw designed for mechanical assemblies where a low-profile head and high clamp load are required. Built from Grade 10.9 alloy steel with a zinc-blue trivalent chromate finish, this fastener offers solid corrosion resistance while meeting RoHS and REACH compliance requirements. The M5x0.8 thread pitch and 20 mm length under head make it a common choice for panel mounting, machinery guards, and general fabrication work. Each package contains 50 screws, making it practical for shop stock or job-lot purchasing.

This screw is suited for use in light industrial, commercial, and trade service applications where a button-head profile is preferred over a standard hex socket cap head. The 4 mm hex drive accepts a standard hex key or bit driver. Full threading along the shank provides maximum thread engagement in through-hole and tapped applications. Technicians working in HVAC equipment assembly, electrical panel fabrication, plumbing fixture mounting, and similar mechanical trades will find this fastener a straightforward fit for routine hardware needs.

Key Features

• Grade 10.9 alloy steel construction for high tensile strength in a compact fastener
• Zinc-blue trivalent chromate finish provides corrosion resistance and meets RoHS and REACH standards
• Fully threaded shank maximizes thread engagement in tapped holes
• 4 mm hex drive compatible with standard hex keys and bit sets
• Conforms to ISO 7380 fastener standard for dimensional consistency
• Sold in a 50-piece package for shop stock or bulk job use

Compatibility

Designed as a standard ISO 7380 button socket cap screw in M5x0.8 thread, suitable for use in any tapped or through-hole application calling for that thread size and a 20 mm length under head.

Installation Notes

Install using a 4 mm hex key or hex bit driver. Ensure the mating tapped hole is clean and the thread class is compatible with M5x0.8 before installation. De-energize any equipment and follow applicable lockout-tagout procedures before fastening or removing hardware on live systems. Do not exceed the rated torque range for Grade 10.9 M5 fasteners as specified by the equipment manufacturer or applicable standards.
