Value Collection 815262PR M20 Hex Head Cap Screw

Product Description

The VALUE COLLECTION 815262PR is a metric hex head cap screw designed for general-purpose fastening in mechanical, structural, and industrial assemblies. Manufactured from Grade 8.8 steel with a zinc-plated finish, this screw delivers reliable tensile strength and basic corrosion resistance suited to indoor and light-duty outdoor applications. The M20 x 2.50 thread profile and 160 mm length under head make it appropriate for heavy fastening tasks where a large-diameter, partially threaded fastener is required. The 30 mm hex drive is compatible with standard metric wrenches and sockets. Trades and assembly professionals install this type of fastener using torque wrenches calibrated to Grade 8.8 specifications per applicable standards.

This screw is used across a wide range of applications including machinery assembly, structural steel connections, equipment mounting, and industrial fabrication. It is suitable for use wherever DIN 931 or ISO 4014 partially threaded hex bolts are specified. The partially threaded shank allows for precise clamp load on bolted joints where full threading would interfere with alignment or shear resistance. Mechanical contractors, millwrights, fabricators, and maintenance technicians are the primary installers of this fastener type.

Installation Notes

Install using a calibrated torque wrench and the appropriate 30 mm metric socket or open-end wrench. Power down and de-energize any associated equipment before beginning fastener installation or removal in mechanical assemblies. Follow Grade 8.8 torque guidelines per the applicable engineering or equipment specification — do not substitute Grade 8.8 hardware in applications specifying higher grades without engineering authorization. Inspect threads and mating surfaces for damage or contamination before assembly.
