Value Collection MKCS08C0409MBPKG M8x1.25 Socket Cap Screw 25pk

Product Description

The VALUE COLLECTION MKCS08C0409MBPKG is a partially threaded socket cap screw engineered for high-strength fastening applications in mechanical assembly, fabrication, and equipment maintenance. Sized at M8x1.25 with a 40 mm length under head, it is manufactured from Grade 12.9 alloy steel, making it one of the strongest standard fastener grades available. The zinc-blue trivalent chromate finish provides corrosion resistance while meeting RoHS and REACH compliance requirements. Driven by a 6 mm internal hex (Allen) drive, this screw is well suited for confined spaces where a socket or hex key is the preferred tool. Each package contains 25 screws.

These socket cap screws are used across a wide range of trade and industrial applications including HVAC equipment assembly, pump and compressor mounting, electrical enclosure fabrication, and general mechanical maintenance. The coarse M8x1.25 thread pitch and partial threading make them appropriate for through-bolt and clearance-hole applications where thread engagement is controlled at the nut or tapped receiving member. They conform to DIN 912 and ISO 4762 fastener standards, ensuring dimensional interchangeability with other compliant hardware.

Key Features

• Grade 12.9 alloy steel construction for high tensile and proof-load strength
• M8x1.25 coarse right-hand thread, partially threaded shaft
• 6 mm hex drive compatible with standard Allen keys and hex bit sockets
• Zinc-blue trivalent chromate finish for corrosion resistance
• RoHS and REACH compliant finish coating
• Conforms to DIN 912 and ISO 4762 fastener standards

Compatibility

Designed as a DIN 912 and ISO 4762 compliant M8x1.25 socket cap screw suitable for any application requiring a partially threaded Grade 12.9 alloy steel fastener with a coarse thread pitch.

Installation Notes

Installation should be performed by a qualified mechanic or technician familiar with metric fastener torque requirements for Grade 12.9 hardware. Ensure the receiving thread or nut is clean and free of debris before installation. Use a properly sized 6 mm hex key or bit socket to avoid rounding the drive. Always consult the equipment manufacturer's torque specifications for the applicable joint before final tightening.
