Value Collection 643772PR Hex Head Cap Screw M20 X 2.50

Product Description

The VALUE COLLECTION 643772PR is a metric hex head cap screw designed for general mechanical fastening applications. Manufactured from Grade 8.8 steel with a bright uncoated finish, this fully threaded fastener measures M20 x 2.50 thread pitch and 110 mm in length under the head. Grade 8.8 steel indicates a medium-high strength carbon steel fastener suitable for structural and machine assembly work. The 30 mm hex drive size accommodates standard industrial wrenches. Manufactured to DIN 933 and ISO 4017 standards, this screw delivers consistent dimensional accuracy for trade and maintenance applications.

This fastener is suited for use in mechanical assembly, structural connections, and equipment maintenance across industrial, commercial, and construction environments. The fully threaded shank allows engagement along the entire bolt length, making it a practical choice for through-bolting applications where maximum thread engagement is required. Maintenance technicians, millwrights, pipefitters, and general contractors commonly use this type of fastener when metric hardware is specified.

Installation Notes

Installation should be performed by qualified trade personnel following applicable mechanical codes and equipment manufacturer specifications. Ensure mating threads are clean and free of debris before installation. Use a calibrated torque wrench and apply the torque value specified by the equipment or structure manufacturer for Grade 8.8 M20 fasteners. Do not substitute a coated or lower-grade fastener where this specification is called out.
