Value Collection 460262BR M20 Hex Cap Screw Grade 10.9 Din 931

Product Description

The VALUE COLLECTION 460262BR is a metric hex head cap screw engineered for high-strength bolted assemblies in industrial, mechanical, and structural applications. Manufactured from Grade 10.9 steel, this fastener delivers tensile strength suited to demanding clamping loads where lower-grade hardware is insufficient. The zinc-plated finish provides a baseline level of corrosion resistance for general shop and field use. With an M20 x 2.50 thread profile, a 160 mm length under head, and a 30 mm hex drive, this screw is sized for heavy mechanical connections. Threading is partial, conforming to DIN 931 dimensional standards. Machinists, millwrights, and maintenance technicians typically install this fastener in fabricated equipment, machinery frames, and structural steel connections.

This screw suits metric-standard bolted joints requiring a coarse M20 x 2.50 thread pitch. The DIN 931 partial-thread configuration leaves a smooth shank section below the head, which is appropriate when the unthreaded portion must pass through a clearance hole before engaging a nut or tapped bore. It is commonly used in machine bases, conveyor frames, heavy equipment assemblies, and structural steel work where a full-thread configuration would be unsuitable. The Grade 10.9 rating places it in the high-strength class, and proper mating hardware of equivalent or higher grade should always be used.

Key Features

• M20 x 2.50 coarse metric thread for standard metric bolted assemblies
• Grade 10.9 steel construction for high-strength clamping force requirements
• Partial threading per DIN 931 with a smooth shank section below the head
• Zinc-plated finish for basic corrosion protection in indoor and general-use environments
• 30 mm hex drive compatible with standard metric hex sockets and wrenches
• 160 mm length under head accommodates thick structural members and stacked components

Compatibility

Designed for use in metric-standard bolted connections requiring an M20 x 2.50 coarse-thread hex head cap screw conforming to DIN 931 dimensions.

Installation Notes

Installation is typically performed by millwrights, maintenance mechanics, or ironworkers using standard metric hex sockets or open-end wrenches. Always verify that mating nuts, washers, and tapped holes carry a compatible metric thread specification and a matching or higher strength grade. Follow applicable torque specifications from the equipment manufacturer or relevant structural standards, as Grade 10.9 fasteners require precise torque to develop correct clamping load. Inspect threads and mating surfaces for damage or contamination before assembly.
