Value Collection MP42756 M8x1.25 Hex Socket Cap Screw 25pk

Product Description

The VALUE COLLECTION MP42756 is a partially threaded hex socket cap screw sized M8 x 1.25 metric with a 50 mm length under head. Manufactured from alloy steel with a black oxide finish coating, this fastener meets DIN 912 and ISO 898-1 standards and carries a material grade of 12.9, indicating high tensile strength suitable for demanding mechanical assemblies. The hex socket drive requires an Allen key or hex bit driver for installation. Each package contains 25 screws, making it practical for production, maintenance, and repair applications across industrial and mechanical trades.

This screw is used in general mechanical assembly, machine component mounting, and structural fastening applications where a high-strength metric cap screw is required. The black oxide coating provides mild corrosion resistance and reduces light reflection in precision assemblies. Machinists, maintenance technicians, and mechanical contractors commonly use this fastener in equipment fabrication, jig and fixture building, and field repair work. The M8 x 1.25 thread pitch is a standard coarse metric thread widely used in machinery manufactured to metric specifications.

Key Features

• M8 x 1.25 metric thread, standard coarse pitch for broad compatibility
• 50 mm length under head, partially threaded shank
• Alloy steel construction with 12.9 material grade for high tensile strength
• Black oxide finish coating for mild corrosion resistance
• Hex socket drive compatible with standard Allen keys and hex bit drivers
• Meets DIN 912 and ISO 898-1 fastener standards

Compatibility

Designed as a standard DIN 912 metric hex socket cap screw suitable for M8 threaded applications in machinery, fixtures, and mechanical assemblies requiring a 12.9 grade alloy steel fastener.

Installation Notes

Installation should be performed by a qualified machinist or mechanical technician using a properly sized hex key or socket bit to avoid rounding the drive recess. Ensure the mating threaded hole is clean and correctly tapped to M8 x 1.25 before driving the fastener. Apply appropriate thread-locking compound or preload torque per the assembly specification for the equipment being serviced. Do not overtighten, as exceeding the design clamp load can damage threads or the mating component.
