Value Collection 460268BR Hex Head Cap Screw M20 X 2.5

Product Description

The VALUE COLLECTION 460268BR is a metric hex head cap screw engineered for high-strength fastening applications in industrial, mechanical, and structural assemblies. Manufactured from Grade 10.9 steel with a zinc-plated finish for corrosion resistance, this screw measures M20 x 2.50 thread pitch with a 180 mm length under head. It is partially threaded per DIN 931 standards and features a 30 mm hex drive. Machinists, millwrights, maintenance technicians, and fabricators install this fastener where high clamping force and resistance to fatigue loads are required.

This screw is suited for heavy-duty bolted connections in manufacturing equipment, steel structures, agricultural machinery, and industrial frames. The M20 x 2.50 thread is a standard coarse metric pitch widely used across European and ISO-compliant equipment platforms. The partial threading per DIN 931 allows the unthreaded shank to carry shear loads, making it appropriate for close-tolerance bolted joints and pivot connections where shear strength matters alongside tensile clamping force.

Key Features

• Grade 10.9 steel construction provides high tensile strength suitable for demanding structural and mechanical joints
• Zinc-plated finish offers baseline corrosion resistance for indoor and sheltered outdoor installations
• Partial threading per DIN 931 allows shank to carry shear loads in close-tolerance assemblies
• M20 x 2.50 coarse thread pitch is a globally standardized metric size compatible with standard M20 nuts and tapped holes
• 30 mm hex drive accommodates standard metric combination wrenches and impact sockets
• 180 mm length under head provides sufficient grip length for thick material stacks and flanged connections

Compatibility

Designed as a standard DIN 931 partially threaded hex head cap screw in M20 x 2.50 for use with any M20 Grade 10 or higher rated nut, washer, or tapped hole conforming to metric coarse thread standards.

Installation Notes

Installation is performed by qualified mechanics, millwrights, or structural technicians using a 30 mm metric wrench or impact socket. Always consult the equipment manufacturer torque specifications for Grade 10.9 M20 fasteners before final tightening. Use appropriate hardened flat washers under the head and nut bearing surfaces to distribute clamping load. Inspect threads for damage before installation and do not reuse fasteners that have been loaded beyond yield.
