Value Collection 460271BR Hex Head Cap Screw M20x2.50x190mm

Product Description

The VALUE COLLECTION 460271BR is a metric hex head cap screw designed for high-strength bolted connections in mechanical, structural, and industrial applications. Built to Grade 10.9 steel with a zinc-plated finish, this fastener delivers the tensile strength required for demanding assemblies where standard-grade hardware falls short. The partially threaded shank follows DIN 931 dimensional standards, providing a consistent bearing surface along the unthreaded portion. At 190 mm under the head with an M20 x 2.50 thread profile, this screw suits heavy-duty joints that require a controlled grip length. Zinc plating provides basic corrosion resistance suitable for dry and mildly exposed environments. Maintenance technicians, millwrights, and industrial mechanics are the primary installers of this fastener class.

This cap screw is appropriate for metric bolted assemblies across manufacturing equipment, structural steel connections, heavy machinery, and general industrial fabrication. The partially threaded design makes it well suited for applications where the bolt passes through a clearance hole and clamps two or more components together without thread engagement through the full length. The 30 mm hex drive accommodates standard metric wrenches and impact sockets commonly used in industrial and mechanical service settings.

Key Features

• Grade 10.9 steel construction for high-strength clamping force
• M20 x 2.50 thread profile per metric standard
• 190 mm length under head for extended grip-length applications
• Partially threaded shank per DIN 931 for controlled bearing surface
• Zinc-plated finish for basic corrosion resistance
• 30 mm hex drive compatible with standard metric wrenches and impact sockets

Compatibility

Designed as a DIN 931-compliant metric hex head cap screw suitable for M20 x 2.50 threaded assemblies requiring a partially threaded, high-strength Grade 10.9 fastener.

Installation Notes

Installation should be performed by qualified mechanics or millwrights 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 installation. Ensure mating threads are clean, undamaged, and free of debris before assembly. Do not substitute this Grade 10.9 fastener in applications specifying lower-grade hardware without engineering review.
