Value Collection 815274PR Hex Head Cap Screw M20 X 2.50

Product Description

The VALUE COLLECTION 815274PR is a metric hex head cap screw engineered for industrial fastening applications requiring a strong, corrosion-resistant connection. Built to Grade 8.8 steel with a zinc-plated finish, this screw delivers reliable tensile strength and moderate corrosion resistance in a range of assembly and structural applications. The fastener is partially threaded with a 200 mm length under head and a 30 mm hex drive, conforming to DIN 931 and ISO 4014 standards. It is installed by mechanics, millwrights, maintenance technicians, and structural assemblers working with metric fastener systems.

This cap screw is suited for general-purpose metric fastening in machinery assembly, structural steel connections, equipment maintenance, and fabrication work where DIN 931 or ISO 4014 compliance is specified. The partial threading is appropriate for applications requiring a grip length — the unthreaded shank bears the shear load while the threaded end secures the nut. Typical install environments include manufacturing floors, mechanical rooms, and field equipment service.

Key Features

• Grade 8.8 steel construction for high tensile and yield strength in demanding fastening applications
• Zinc-plated finish provides moderate corrosion resistance and a clean appearance
• Partially threaded shank allows for shear-bearing grip length in structural connections
• Conforms to DIN 931 and ISO 4014 dimensional and mechanical standards
• 30 mm hex drive accommodates standard metric wrenches and sockets
• M20 x 2.50 thread size is a widely used coarse-pitch metric fastener profile

Compatibility

Designed as a standard metric replacement or new-installation fastener for applications specifying an M20 x 2.50 x 200 mm hex head cap screw per DIN 931 or ISO 4014.

Installation Notes

Installation should be performed by qualified mechanics or technicians familiar with metric fastener standards. Always verify mating thread pitch and class before installation to avoid cross-threading or mismatched clamping loads. Use a calibrated torque wrench appropriate for M20 fasteners and follow the torque specifications provided by the equipment manufacturer or applicable engineering standard. De-energize or lock out any equipment before servicing fasteners on live machinery per OSHA lockout/tagout requirements.
