Value Collection MKCS08C1009MBPKG M8x1.25 Cap Screw 10-pack

Product Description

The VALUE COLLECTION MKCS08C1009MBPKG is an M8x1.25 socket cap screw designed for high-strength mechanical fastening applications. Manufactured from grade 12.9 alloy steel with a zinc-blue trivalent chromate finish, this screw delivers excellent tensile strength and corrosion resistance. The partially threaded shank provides a clamp load advantage in bolted joint assemblies where shank clearance fit is critical. The hex drive socket accepts a 6 mm hex key for precise torque application. Sold in a package of 10 pieces, this screw is suited for use by maintenance technicians, millwrights, and mechanical contractors working on equipment assemblies, machinery, and structural fixturing.

This socket cap screw is appropriate for use in industrial, commercial, and light manufacturing environments. The partially threaded configuration makes it well suited for through-bolt applications where the unthreaded shank spans a clearance hole, reducing stress concentrations at the joint interface. The coarse M8x1.25 thread pitch allows for fast installation and reliable engagement in tapped steel or ductile iron components. Grade 12.9 material grade makes this screw appropriate for high-load, high-vibration environments common in mechanical equipment service and repair.

Key Features

• Grade 12.9 alloy steel construction for high tensile and proof load capacity
• Zinc-blue trivalent chromate finish provides corrosion resistance and is RoHS and REACH compliant
• Partially threaded shank suits through-bolt and precision clearance-fit joint applications
• 6 mm hex drive socket for standard hex key or Allen-drive tooling
• Coarse M8x1.25 thread pitch for fast engagement and reliable torque transfer
• Conforms to DIN 912 and ISO 4762 fastener standards

Compatibility

Designed as a standard DIN 912 and ISO 4762 socket head cap screw for use in any tapped M8x1.25 coarse-pitch hole in steel, iron, or compatible structural materials requiring a grade 12.9 fastener.

Installation Notes

Installation is performed by qualified mechanical technicians or millwrights using a 6 mm hex key or Allen-drive bit. De-energize and lock out all equipment before servicing fastened assemblies per applicable OSHA lockout/tagout procedures. Do not mix grade 12.9 screws with lower-grade hardware in the same joint without engineering review. Apply thread lubricant only when specified by the equipment manufacturer, as lubrication significantly affects torque-to-clamp-load relationships for high-strength fasteners.
