Value Collection 44642 M20 Hex Cap Screw Grade 10.9 Din 931

Product Description

The Value Collection 44642 is a metric hex head cap screw designed for high-strength bolted connections in mechanical, structural, and industrial assemblies. Manufactured from Grade 10.9 steel with a zinc-plated finish, it delivers a strong corrosion-resistant fastener suited for demanding applications. The screw measures M20 x 2.50 thread pitch with a 100 mm length under head and is partially threaded per DIN 931 standards. A 30 mm hex drive size accommodates standard metric wrenches or impact tooling. This fastener is installed by millwrights, maintenance mechanics, and assembly technicians working in metric-standard environments.

This screw is appropriate for medium to heavy-duty bolted joints where a partially threaded shank is required to allow proper clamp load distribution across the grip length. Typical applications include machinery frames, structural steel connections, equipment mounting, and fabrication assemblies requiring metric fasteners conforming to DIN 931. The zinc plating provides moderate corrosion resistance suitable for indoor or lightly exposed environments. Packaged in quantities of 5 per pack with a minimum order quantity of 1 pack.

Compatibility

Designed as a DIN 931 metric hex head cap screw for use in any M20 x 2.50 threaded application requiring Grade 10.9 strength classification and partial threading.

Installation Notes

Installation should be performed by qualified mechanics or assembly technicians familiar with metric fastener torque requirements for Grade 10.9 hardware. Always consult the equipment manufacturer or applicable engineering specifications for proper torque values before tightening. Use a calibrated torque wrench or impact driver with a 30 mm metric socket. Inspect threads in the mating component for damage or contamination before installation to ensure full thread engagement and proper clamp load.
