Value Collection -42759-1 M8x1.25 Hex Socket Cap Screw

Product Description

The VALUE COLLECTION -42759-1 is a partially threaded hex socket cap screw built to DIN 912 and ISO 898-1 standards. It features an M8 x 1.25 metric thread and measures 90 mm in length under the head. Constructed from alloy steel with a material grade of 12.9, it delivers high tensile strength suited for demanding fastening applications. The black oxide finish provides moderate corrosion resistance and reduces light reflection. This fastener is installed using a hex (Allen) key drive and is supplied in quantities sold as multiples of 25 units per order.

This screw is well suited for mechanical assemblies, machine component mounting, and industrial equipment where high-strength metric fasteners are required. The partial threading allows for precise load transfer in through-hole and clearance-hole applications. It is commonly used in manufacturing, maintenance, and repair settings by machinists, millwrights, and general industrial technicians working with metric hardware.

Key Features

• M8 x 1.25 metric thread with 90 mm length under head
• Partially threaded shank for clearance-hole fastening
• Alloy steel construction at material grade 12.9 for high tensile strength
• Black oxide finish for corrosion resistance and low reflectivity
• Hex socket (Allen key) drive type
• Meets DIN 912 and ISO 898-1 fastener standards

Compatibility

Designed as a standard DIN 912 metric hex socket cap screw suitable for applications requiring M8 x 1.25 grade 12.9 alloy steel fasteners in industrial and mechanical assemblies.

Installation Notes

Installation requires an appropriately sized hex (Allen) key or socket driver. Ensure mating threads are clean and free of debris before installation. Follow applicable torque guidelines from the relevant engineering or equipment specifications for grade 12.9 M8 fasteners. Always use proper personal protective equipment when working with high-strength fasteners under load.
