Value Collection 42751 M8x1.25 Hex Socket Cap Screw

Product Description

The VALUE COLLECTION 42751 is a metric hex socket cap screw designed for high-strength fastening applications in mechanical assemblies, tooling, and equipment maintenance. Sized M8 x 1.25 with a 25 mm length under head, this screw is fully threaded and manufactured from alloy steel with a black oxide finish. It meets DIN 912 and ISO 898-1 standards and carries a material grade of 12.9, indicating high tensile strength suitable for demanding mechanical joints. The drive type is internal hex, requiring a hex key or Allen wrench for installation. This fastener is well suited for professionals in mechanical, industrial, and HVAC applications where reliable, torque-rated fasteners are required.

This screw is used in a wide range of commercial and industrial assembly applications, including machine frames, equipment panels, motor mounts, and mechanical enclosures. The M8 x 1.25 thread size is a common metric standard across European and Asian-manufactured equipment, making this a practical stock fastener for maintenance shops, service fleets, and trade professionals who work on metric machinery and HVAC or refrigeration equipment with metric hardware.

Key Features

• M8 x 1.25 metric thread, fully threaded along the 25 mm shank length under head
• Grade 12.9 alloy steel construction for high tensile and shear strength
• Black oxide finish provides mild corrosion resistance and reduces surface glare
• Internal hex drive type compatible with standard hex keys and Allen wrenches
• Conforms to DIN 912 and ISO 898-1 fastener standards

Compatibility

Designed as a standard metric replacement or stock fastener for any assembly requiring an M8 x 1.25 hex socket cap screw per DIN 912 specifications.

Installation Notes

Installation should be performed by a qualified mechanic or technician using a calibrated torque wrench and the appropriate metric hex key or bit. Always verify thread engagement depth and mating material before torquing. Do not mix metric and imperial fasteners in the same joint. For critical structural applications, follow the equipment manufacturer's torque specifications for grade 12.9 M8 fasteners.
