Value Collection MKCS05C0809MBPKG M5x0.8 Socket Cap Screw

Product Description

The VALUE COLLECTION MKCS05C0809MBPKG is an M5x0.8 socket cap screw designed for precision fastening in mechanical assemblies, fixtures, and equipment. The screw features a partially threaded shank, a 4 mm internal hex drive, and an 80 mm length under head. Built from grade 12.9 alloy steel with a zinc-blue trivalent chromate finish, it delivers high tensile strength and corrosion resistance. The trivalent chromate coating is RoHS and REACH compliant. This fastener suits applications where high clamping force and a low-profile cap head are required. Sold in a package of 25.

This socket cap screw is used across a wide range of industrial and mechanical applications including HVAC equipment assembly, pump and motor mounting, panel fabrication, and general machine maintenance. The M5 coarse thread pitch and grade 12.9 material rating make it appropriate for high-stress joints where standard steel fasteners would be underspec. The right-hand thread direction follows standard assembly conventions. Technicians and maintenance professionals working on light to medium mechanical assemblies will find this screw compatible with common metric hardware configurations.

Key Features

• M5x0.8 coarse right-hand thread for standard metric compatibility
• Grade 12.9 alloy steel construction for high tensile and proof load strength
• 80 mm length under head with partial threading for precise clamping control
• 4 mm hex drive socket head for use with standard Allen wrenches and hex bit drivers
• Zinc-blue trivalent chromate finish provides corrosion resistance and is RoHS and REACH compliant
• Meets DIN 912 and ISO 4762 fastener standards

Compatibility

Designed as a standard DIN 912 and ISO 4762 metric socket cap screw suitable for M5x0.8 threaded holes in mechanical equipment, fixtures, and assemblies requiring grade 12.9 fasteners.

Installation Notes

Installation is typically performed by maintenance technicians or mechanical assemblers using a 4 mm hex key or Allen bit driver. Ensure threaded holes are clean and free of debris before installation. Always verify that the mating thread pitch and material rating are appropriate for the joint load requirements before final assembly. Do not mix metric and imperial fasteners in the same assembly.
