Value Collection 42216 M20x2.5x120mm Hex Cap Screw Gr8.8

Product Description

The Value Collection 42216 is a metric hex head cap screw designed for general industrial and structural fastening applications. It features an M20 x 2.50 thread with a 120 mm length under head and a 30 mm hex drive size. Manufactured from Grade 8.8 steel with a zinc-plated finish, this screw delivers solid mechanical strength and basic corrosion resistance suitable for most indoor and light-duty outdoor installations. Threading is partial per DIN 931 and ISO 4014 standards, which allows the unthreaded shank to bear shear loads in bolted joints. This package contains 3 screws.

This screw is used in mechanical assemblies, equipment fabrication, structural connections, and maintenance applications where metric fasteners are specified. The partially threaded shank makes it well suited for through-bolt applications where shear resistance is required alongside clamping force. It is installed by maintenance technicians, millwrights, fabricators, and industrial mechanics working with metric-standard equipment and machinery.

Key Features

• Zinc-plated finish offers basic corrosion resistance for indoor and light outdoor environments
• Partially threaded shank per DIN 931 and ISO 4014 standards supports shear load applications
• 30 mm hex drive accommodates standard industrial wrenches and sockets
• Package of 3 screws with a minimum order quantity of 1

Compatibility

Designed as an OEM-style metric fastener for use in any application requiring a DIN 931 or ISO 4014 compliant M20 x 2.50 partially threaded hex head cap screw in Grade 8.8 steel.

Installation Notes

Installation should be performed by qualified mechanics or fabricators familiar with metric fastener specifications and torque requirements. Always confirm the mating thread and material before installation to avoid galling or cross-threading. Use calibrated torque tools when applying final clamp load to Grade 8.8 fasteners. Do not substitute this fastener in applications specifying a higher strength grade such as Grade 10.9 or Grade 12.9 without engineering review.
