Value Collection 643175PR Hex Head Cap Screw M16x2 90mm

Product Description

The VALUE COLLECTION 643175PR is a metric hex head cap screw designed for general-purpose mechanical fastening in structural, industrial, and machine assembly applications. Built to Grade 8.8 steel with a bright uncoated finish, this fully threaded fastener meets DIN 933 and ISO 4017 standards. The M16 x 2.00 thread pitch paired with a 90 mm length under head makes it a common choice for mid-load bolted connections where metric fasteners are specified. A 24 mm hex drive accepts standard metric wrenches and sockets. Machinists, millwrights, and maintenance technicians typically install this type of fastener across a wide range of equipment and fabrication work.

This fastener suits residential and commercial mechanical assemblies, structural steel connections, equipment mounting, and general industrial maintenance. Fully threaded along its 90 mm shank length, it provides consistent thread engagement through the full grip range. Applications include machinery frames, brackets, and flanged connections where DIN 933 or ISO 4017 compliance is required. The bright uncoated finish is appropriate for indoor or protected environments where corrosion exposure is minimal.

Installation Notes

Millwrights, maintenance technicians, and fabricators install this fastener using a 24 mm wrench or socket driver. Power down and de-energize any equipment before disassembling or reassembling bolted assemblies. Apply torque values in accordance with the equipment manufacturer specifications for Grade 8.8 M16 fasteners — do not substitute torque values from other grade classes. Follow applicable mechanical and structural codes for the installation environment.
