Value Collection 42170 Hex Head Cap Screw M16x2 50mm

Product Description

The VALUE COLLECTION 42170 is a metric hex head cap screw designed for general-purpose fastening applications requiring a partially threaded shank and precise metric engagement. Built to Grade 8.8 steel specification, this fastener delivers a tensile strength suitable for structural and mechanical assemblies across industrial, commercial, and maintenance environments. The M16 x 2.00 thread form and 50 mm length under head conform to DIN 931 and ISO 4014 standards. A zinc-plated finish provides a baseline level of corrosion resistance for indoor and light-duty outdoor use. The 24 mm hex drive accepts standard metric wrenches and sockets for straightforward installation.

This screw is used in machine assembly, structural steel connections, equipment mounting, and general mechanical fabrication where a partially threaded, metric hex head fastener is required. The partially threaded shank allows clamping force to be applied across the unthreaded grip length, making it well suited for bolted joint assemblies where shear load distribution matters. Licensed mechanics, millwrights, pipefitters, and maintenance technicians commonly install this fastener in manufacturing, processing, and heavy equipment applications.

Key Features

• Grade 8.8 steel construction meets recognized strength classification for medium-high tensile fasteners
• M16 x 2.00 metric thread form conforms to DIN 931 and ISO 4014 standards
• 50 mm length under head with partially threaded shank for proper grip-length clamping
• Zinc-plated finish provides corrosion resistance for general service conditions
• 24 mm hex head accepts standard metric drive tools

Compatibility

Designed as an OEM-style and general replacement metric hex head cap screw for applications conforming to DIN 931 and ISO 4014 fastener standards in M16 x 2.00 thread size.

Installation Notes

Installation should be performed by qualified personnel following applicable mechanical and structural codes for the application. Always de-energize or shut down equipment before servicing fastened assemblies. Use calibrated torque tools appropriate for Grade 8.8 fasteners and the joint design requirements. Do not mix metric and unified thread components in the same assembly.
