Value Collection 830920BR Hex Head Cap Screw M20 X 2.50

Product Description

The VALUE COLLECTION 830920BR is a metric hex head cap screw manufactured from 18-8 austenitic Grade A2 stainless steel. It features a partially threaded shank with an M20 x 2.50 thread profile and a 95 mm length under the head. The 30 mm hex drive size accommodates standard metric wrenches. Grade A2 stainless steel provides solid corrosion resistance in wet, chemical-adjacent, or outdoor environments. This fastener conforms to DIN 931 and DIN 933 standards, making it a reliable choice for structural, mechanical, and industrial assembly applications where dimensional accuracy and material grade documentation matter.

This screw is suited for bolted connections in mechanical assemblies, structural steel fabrication, equipment mounting, and general industrial maintenance. The partially threaded shank allows the unthreaded grip section to bear shear loads while the threaded portion engages a nut or tapped hole. It is installed by machinists, millwrights, maintenance technicians, and trade professionals working on metric-dimensioned equipment or fabricated steel structures where DIN-standard fasteners are specified.

Key Features

• M20 x 2.50 thread size with 95 mm length under head for deep grip applications
• Partially threaded shank allows unthreaded section to carry shear loads
• 18-8 austenitic Grade A2 stainless steel for corrosion resistance
• 30 mm hex drive compatible with standard metric box-end and socket wrenches
• Conforms to DIN 931 and DIN 933 dimensional standards
• UNSPSC Code 31161501 for streamlined procurement and classification

Compatibility

Designed for use in metric-dimensioned assemblies requiring an M20 x 2.50 partially threaded hex head cap screw per DIN 931 and DIN 933 specifications.

Installation Notes

Installation is typically performed by machinists or maintenance technicians using a metric socket or box-end wrench sized to the 30 mm hex. Verify that the mating nut or tapped hole matches the M20 x 2.50 thread pitch before assembly. Apply thread lubricant or anti-seize compound appropriate for stainless steel fasteners to reduce the risk of galling during installation. Follow applicable equipment manufacturer torque requirements and relevant fastener standards for the specific assembly.
