Value Collection 460265BR M20 Hex Cap Screw Grade 10.9 Din 931

Product Description

The VALUE COLLECTION 460265BR is a metric hex head cap screw engineered for high-strength bolted assemblies. Manufactured from Grade 10.9 steel with a zinc-plated finish, this fastener delivers reliable clamping force in demanding structural and mechanical applications. The screw measures M20 x 2.50 thread pitch with a 170 mm length under head and features partial threading per DIN 931, the standard for partially threaded metric hex bolts. The 30 mm hex drive size suits standard heavy-duty wrenching. Grade 10.9 indicates a high-tensile alloy steel with a minimum tensile strength of 1040 MPa, making it appropriate for critical joint applications where bolt integrity is essential.

This fastener is used in industrial machinery, structural steel fabrication, heavy equipment assembly, and general mechanical maintenance where metric fasteners are required. The partial thread design provides a smooth shank section that resists shear loads, making it well suited for bolted connections that experience lateral forces. Maintenance technicians, millwrights, and fabricators working on metric-specification equipment will find this screw a direct-fit solution for M20 applications governed by DIN standards.

Key Features

• Grade 10.9 high-tensile steel construction for demanding load-bearing applications
• Zinc-plated finish provides basic corrosion resistance in indoor and sheltered environments
• Partially threaded per DIN 931 standard, providing a full shank section for shear-load resistance
• M20 x 2.50 thread pitch with 170 mm length under head for deep-reach bolting needs
• 30 mm hex size compatible with standard metric wrenches and sockets
• Sold individually, allowing single-unit procurement or small-quantity replacement

Compatibility

Designed as a DIN 931-compliant partially threaded metric hex cap screw for M20 x 2.50 applications in industrial, structural, and mechanical assemblies requiring Grade 10.9 fastener specifications.

Installation Notes

Installation is typically performed by millwrights, maintenance mechanics, or qualified fabricators using a 30 mm combination wrench or socket with a calibrated torque wrench. Always verify the mating nut or threaded hole is also rated for Grade 10.9 or higher to prevent thread stripping under load. De-energize and lock out all equipment before replacing fasteners on machinery per applicable safety standards. Do not substitute a lower-grade fastener in applications that specify Grade 10.9.
