Value Collection 643226PS M20 Hex Head Cap Screw Grade 8.8

Product Description

The VALUE COLLECTION 643226PS is a metric hex head cap screw designed for general mechanical fastening applications. It is fully threaded along its 40 mm length under head and features an M20 x 2.50 mm thread profile. The fastener is manufactured from Grade 8.8 steel, which provides a tensile strength suitable for medium-to-high load structural and mechanical assemblies. The bright uncoated finish leaves the steel in its natural state, making it appropriate for dry or controlled-environment installations where coating is not required or where the assembler will apply their own treatment. A 30 mm hex drive allows standard open-end or socket wrenches to be used during installation.

This cap screw is suited for use in machinery assembly, structural steel connections, equipment mounting, and general fabrication work where metric fasteners conforming to DIN 933 and ISO 4017 standards are specified. It is a common hardware item in industrial maintenance, mechanical contracting, and facilities work. Trade professionals, millwrights, and maintenance mechanics will find it a straightforward replacement or build-out fastener wherever an M20 fully threaded hex bolt is called for in a metric specification.

Compatibility

Designed as an OEM-style replacement or standard build fastener for metric mechanical assemblies requiring a fully threaded M20 x 2.50 mm hex head cap screw per DIN 933 or ISO 4017 specifications.

Installation Notes

Installation is typically performed by millwrights, mechanical contractors, or maintenance technicians using a standard 30 mm open-end or socket wrench. Always power down and de-energize any equipment before accessing fastened assemblies. Apply thread lubricant or anti-seize only if specified by the equipment manufacturer, as doing so affects clamp load. Torque to the value specified in the equipment or structural design documentation, not a generic value, since joint requirements vary by application.
