Value Collection 460280BR M20 Hex Cap Screw Grade 10.9

Product Description

The VALUE COLLECTION 460280BR is a metric hex head cap screw engineered for high-strength fastening applications across industrial, mechanical, and structural assemblies. This screw features an M20 x 2.50 thread profile with a 220 mm length under head and is manufactured from Grade 10.9 steel, placing it in the high-tensile category suitable for demanding load-bearing connections. A zinc-plated finish provides baseline corrosion resistance for general-purpose use. The partial threading configuration follows DIN 931 standards, making it appropriate for applications requiring a smooth shank section between the bearing surface and threaded engagement zone. Millwrights, maintenance technicians, and mechanical contractors are the typical installers.

This fastener is suited for use in metric-dimensioned machinery, structural steel connections, heavy equipment assemblies, and industrial fabrication applications where high clamping force is required. The M20 diameter and 220 mm length make it appropriate for thick-section bolted joints where grip length and thread engagement depth are critical design factors. Partial threading per DIN 931 is commonly specified in engineering drawings for bolted connections involving shear loading or close-tolerance holes.

Key Features

• Grade 10.9 steel construction for high tensile strength and reliable clamping performance
• M20 x 2.50 thread size conforming to metric thread standards
• 220 mm length under head with partial threading per DIN 931
• Zinc-plated finish for general corrosion protection
• 30 mm hex drive size for use with standard metric wrenches and sockets

Compatibility

Designed as a DIN 931 partially threaded metric hex head cap screw for use in metric-dimensioned bolted assemblies requiring M20 x 2.50 thread engagement.

Installation Notes

Installation should be performed by qualified mechanical or structural technicians following applicable engineering specifications and torque requirements for Grade 10.9 fasteners. Always verify thread engagement depth and hole clearance before installation. Use a calibrated torque wrench to achieve the required clamp load as specified by the equipment manufacturer or applicable structural design standards. Do not substitute this fastener into applications rated for higher or lower material grades without verifying compatibility with a qualified engineer.
