Value Collection 815804PR Hex Head Cap Screw M8 X 1.25

Product Description

The VALUE COLLECTION 815804PR is a metric hex head cap screw engineered for general-purpose fastening in industrial, mechanical, and structural assemblies. It features an M8 x 1.25 mm thread with a 55 mm length under head and is fully threaded along its entire shank. Manufactured from Grade 8.8 steel, this fastener delivers reliable tensile strength appropriate for medium-duty bolted joints. A zinc-plated finish provides basic corrosion resistance for use in dry to mildly humid environments. The 13 mm hex drive is compatible with standard metric wrenches and sockets. This screw conforms to DIN 933 and ISO 4017 standards.

This fastener is suited for a wide range of metric bolted connections in manufacturing, equipment assembly, maintenance, and repair applications. It is commonly used in fabricated steel structures, machinery frames, brackets, and general mechanical assemblies where a fully threaded metric hex cap screw is required. The Grade 8.8 rating makes it appropriate for applications requiring moderate clamping force without the overhead of high-strength alloy fasteners. Installation is performed using standard hand or power tools with a 13 mm hex socket or wrench.

Compatibility

Designed as a standard metric hex head cap screw suitable for any assembly requiring an M8 x 1.25 fully threaded fastener per DIN 933 or ISO 4017 specifications.

Installation Notes

Installation is typically performed by a mechanic, millwright, or maintenance technician using a 13 mm metric socket or combination wrench. Always ensure mating threads are clean and free of debris before installation. Do not exceed the torque rating appropriate for Grade 8.8 M8 fasteners as specified by the equipment manufacturer or applicable engineering standards. Use a calibrated torque wrench for critical joint applications.
