Value Collection MKCS08C0509MBPKG M8x1.25 Socket Cap Screw 25pk

Product Description

The VALUE COLLECTION MKCS08C0509MBPKG is a partially threaded socket cap screw with an M8x1.25 thread and a 50 mm length under head. Made from grade 12.9 alloy steel with a zinc-blue trivalent chromate finish, it delivers high tensile strength and corrosion resistance suited for demanding mechanical and structural assemblies. The hex drive accepts a 6 mm hex key. Each package contains 25 screws. This fastener is RoHS and REACH compliant, making it appropriate for assemblies with environmental material restrictions. Machinists, millwrights, and industrial maintenance technicians are the primary installers.

This socket cap screw is used in general mechanical assemblies, machine frames, brackets, and equipment panels where a recessed hex-drive fastener is required. The partial threading provides a smooth shank section useful for applications requiring a shoulder bearing surface or precise hole alignment. The coarse M8x1.25 thread pitch is standard for most metric-tapped holes in that size range across light industrial and commercial equipment.

Key Features

• Grade 12.9 alloy steel for high tensile strength in load-bearing assemblies
• Zinc-blue trivalent chromate finish provides corrosion resistance and RoHS compliance
• Partially threaded shank aids alignment and provides a bearing surface in clearance-hole applications
• 6 mm hex drive for standard hex key installation
• Right-hand, coarse M8x1.25 thread matches widely used metric tapped holes
• Meets DIN 912 and ISO 4762 fastener standards

Compatibility

Designed for metric-tapped M8x1.25 coarse-thread holes in mechanical assemblies, equipment frames, and machinery per DIN 912 and ISO 4762 standards.

Installation Notes

Installation is performed by machinists, millwrights, or maintenance technicians using a 6 mm hex key or hex bit driver. Verify the receiving hole is tapped to M8x1.25 coarse thread and is free of debris before driving the fastener. Do not exceed the rated torque specification for grade 12.9 M8 fasteners as defined by the applicable engineering standard or equipment manufacturer. Power down or de-energize any equipment before accessing fastener locations on live assemblies.
