Value Collection 644355PR Hex Cap Screw M12x1.75x140mm

Product Description

The VALUE COLLECTION 644355PR is a metric hex head cap screw designed for general mechanical fastening applications. Built to Grade 8.8 steel specifications, this screw delivers reliable tensile strength suitable for structural and machine assembly work. The partially threaded shank measures 140 mm under the head with an M12 x 1.75 thread form, conforming to DIN 931 and ISO 4014 standards. The 19 mm hex drive allows installation with standard metric wrenches and sockets. The bright, uncoated finish is suitable for use in dry or controlled environments. Machinists, millwrights, and maintenance technicians commonly specify this fastener for bolted joint assemblies in steel fabrication and equipment manufacturing.

This cap screw is suited for medium to heavy-duty bolted connections in industrial, agricultural, and commercial equipment. Partial threading is appropriate where a smooth shank section is needed through a clearance hole before engaging the threaded portion. The DIN 931 and ISO 4014 standard dimensions make this screw interchangeable with metric-spec hardware sourced globally. Sold individually with a minimum order quantity of 25 pieces.

Installation Notes

Installation should be performed by a qualified mechanic or millwright using a calibrated torque wrench sized for a 19 mm hex. Always de-energize and lock out equipment before servicing bolted joints on machinery. Apply torque values appropriate for Grade 8.8 M12 fasteners as specified in the equipment manufacturer's documentation. Inspect threads for damage before installation and ensure mating nut or tapped hole conforms to M12 x 1.75 tolerances.
