Value Collection 643109PR Hex Head Cap Screw M12x1.75x20mm Grade 8.8

Product Description

The VALUE COLLECTION 643109PR is a metric hex head cap screw engineered for general industrial and mechanical fastening applications. Manufactured from Grade 8.8 steel with a bright, uncoated finish, this fully threaded fastener measures M12 x 1.75 thread pitch with a 20 mm length under head and a 19 mm hex drive size. Grade 8.8 designates a medium-high strength carbon steel fastener suitable for structural assemblies, machinery, and equipment where consistent clamping force is required. Compliance with DIN 933 and ISO 4017 standards ensures dimensional accuracy and interchangeability across metric fastener applications.

This fastener is used in a wide range of industrial, mechanical, and maintenance applications where a fully threaded metric hex cap screw is specified. The M12 x 1.75 thread size is common in machine frames, fabricated steel assemblies, automotive equipment, and general manufacturing. The fully threaded shank provides consistent thread engagement across the full grip length, making it well suited for applications where the fastener threads into a tapped hole or is used with a nut and washer arrangement. Minimum order quantity is 100 pieces per order.

Installation Notes

Installation is typically performed by a mechanic, millwright, or maintenance technician using a standard 19 mm hex wrench or socket. Always ensure the mating tapped hole or nut thread is clean and free of debris before installation. De-energize and lock out equipment before servicing any mechanical assembly. Do not exceed the torque specifications published in the applicable equipment service documentation for Grade 8.8 M12 fasteners.
