Value Collection 42206 M20 X 2.50 X 50 Mm Hex Cap Screw 5 Pack

Product Description

The Value Collection 42206 is a fully threaded hex head cap screw engineered to metric dimensional standards and intended for use in structural and mechanical fastening applications. The fastener is manufactured from Grade 8.8 steel, a medium-carbon alloy heat-treated to deliver a minimum tensile strength appropriate for demanding bolted assemblies. A zinc-plated finish provides a baseline level of corrosion resistance suitable for general indoor and light-duty outdoor use. The screw measures M20 x 2.50 thread size with a 50 mm length under the head, and carries a 30 mm hex drive. It conforms to DIN 933 and ISO 4017 standards. Sold in a pack of 5 units per order.

This fastener is used across a wide range of industrial, mechanical, and construction applications where metric hardware is specified. Common install scenarios include machinery assembly, structural steel connections, equipment mounting, and general fabrication work. The fully threaded shank provides consistent clamping engagement along the full bolt length, making it well suited for through-bolting applications with a nut or into a threaded hole. Trades that typically specify Grade 8.8 metric fasteners include millwrights, pipefitters, ironworkers, and industrial maintenance technicians.

• Fully threaded shank per DIN 933 and ISO 4017 standards
• Zinc-plated finish for baseline corrosion protection in general service environments
• 30 mm hex drive size compatible with standard metric wrenches and sockets
• Sold in a 5-piece pack to support small-quantity procurement

Compatibility

Designed as a standard metric hex head cap screw conforming to DIN 933 and ISO 4017, suitable for use in any application specifying a fully threaded M20 x 2.50 Grade 8.8 fastener.

Installation Notes

Installation should be performed by a qualified mechanic, millwright, or maintenance technician familiar with metric fastener specifications. Always verify thread engagement depth and mating thread condition before torquing. Apply torque values per the applicable engineering specification or fastener manufacturer torque chart for Grade 8.8 hardware at M20 size. Inspect the zinc-plated finish for damage before installation, as compromised coating may reduce corrosion resistance in moisture-exposed environments.
