Value Collection MP42758-1 M8x1.25 Hex Socket Cap Screw

Product Description

The VALUE COLLECTION MP42758-1 is a metric hex socket cap screw designed for high-strength fastening applications across industrial, mechanical, and trade installations. It features an M8 x 1.25 thread size with a 75 mm length under head and is partially threaded along the shank. Manufactured from alloy steel with a black oxide coating, this fastener carries a material grade of 12.9, indicating high tensile strength suitable for demanding clamping and assembly work. Licensed trades and maintenance professionals rely on this grade for critical bolted joints where standard hardware grades are insufficient.

This screw is suited for general mechanical assemblies, HVAC equipment mounting, electrical enclosure hardware, pump and motor fastening, and similar trade applications where metric fasteners are specified. The hex socket drive requires a standard metric hex key or Allen driver, making it compatible with common hand and power tool setups. It conforms to DIN 912 and ISO 898-1 standards, which are widely referenced in OEM equipment service documentation and engineering drawings.

Key Features

• M8 x 1.25 thread size with 75 mm length under head
• Partially threaded shank for precise clamping in through-bolt applications
• Alloy steel construction with 12.9 material grade for high tensile strength
• Black oxide finish provides mild corrosion resistance and reduces glare
• Hex socket drive for use with metric Allen keys and hex bit drivers
• Conforms to DIN 912 and ISO 898-1 fastener standards

Compatibility

Designed as an OEM-style metric hex socket cap screw for mechanical assemblies and trade equipment requiring M8 x 1.25 DIN 912 grade 12.9 fasteners.

Installation Notes

Installation should be performed by qualified mechanical or trade personnel familiar with metric fastener specifications. Ensure mating threads are clean and free of debris before driving. Use a calibrated torque wrench sized for M8 fasteners and refer to equipment OEM torque specifications for the joint being assembled. Do not substitute a lower-grade fastener in any application originally specified for 12.9 hardware.
