Value Collection MP42747 Hex Socket Cap Screw M8 X 1.25

Product Description

The VALUE COLLECTION MP42747 is a metric hex socket cap screw designed for high-strength fastening applications across industrial, mechanical, and trade assembly work. Sized M8 x 1.25 with a 16 mm length under head, this fastener is fully threaded and manufactured from alloy steel to material grade 12.9 — one of the highest strength grades available for metric fasteners. A black oxide finish provides mild corrosion resistance and a clean, low-reflectance appearance. Technicians and assemblers rely on this screw anywhere a high-clamp-load, hex-drive fastener is required in a compact footprint.

This screw is suited for use in mechanical assemblies, equipment fabrication, maintenance repairs, and structural fastening where grade 12.9 alloy steel is specified. The internal hex drive accepts a standard metric hex key or Allen driver, making installation practical in recessed or tight-clearance locations. It conforms to DIN 912 and ISO 898-1 standards, making it interchangeable with other fasteners manufactured to those specifications. Typical applications include machinery, brackets, flanges, and general metalwork requiring a high-tensile metric cap screw. This item is sold in minimum quantities of 25 pieces per order.

Compatibility

Designed as a standard DIN 912 metric hex socket cap screw compatible with M8 x 1.25 threaded holes in equipment, assemblies, and structures requiring grade 12.9 alloy steel fasteners.

Installation Notes

Installation is performed with a metric hex key or Allen driver sized for M8 socket cap screws. Ensure mating threads are clean and free of debris before driving. Grade 12.9 fasteners require appropriate preload based on joint engineering — do not substitute torque values from lower-grade fastener specifications. Follow applicable mechanical or structural assembly codes for the equipment or application being serviced.
