Value Collection SCX220040-001BX M20 Hex Socket Cap Screw

Product Description

The VALUE COLLECTION SCX220040-001BX is a fully threaded hex socket cap screw sized M20 x 2.50 metric with a 40 mm length under head. Manufactured from 18-8 austenitic stainless steel (Material Grade A2) with a bright uncoated finish, this fastener meets DIN 912 standards. It is driven with a hex (Allen) key and is well suited for high-strength bolted connections in industrial, mechanical, and structural assemblies where corrosion resistance is required. Licensed tradespeople, millwrights, pipefitters, and maintenance technicians commonly specify this grade of fastener in demanding service environments.

This screw is appropriate for use in both light industrial and heavy-duty mechanical assemblies where metric fasteners and corrosion resistance are specified. The M20 x 2.50 thread pitch and 40 mm shank length make it a common selection for flanged connections, machine bases, structural brackets, and equipment mounting applications. The fully threaded shank provides maximum thread engagement throughout the clamped joint. It is packaged individually and sold in single-unit quantities.

Key Features

• M20 x 2.50 metric thread size for compatibility with standard metric hardware
• 40 mm length under head, fully threaded for maximum thread engagement
• 18-8 austenitic stainless steel construction, Material Grade A2, for corrosion resistance
• Bright uncoated finish — no coating buildup on threads
• Hex socket drive for torque application with a standard Allen key or hex bit
• Manufactured to DIN 912 fastener standard

Compatibility

Designed as a standard DIN 912 metric hex socket cap screw suitable for M20 x 2.50 threaded assemblies in industrial, mechanical, and structural applications requiring Grade A2 stainless steel fasteners.

Installation Notes

Installation should be performed by a qualified mechanic, millwright, or maintenance technician familiar with metric fastener torque requirements for M20 hardware. Use a properly sized hex key or socket bit to avoid cam-out and thread galling, which is a known risk with stainless steel fasteners — apply an anti-seize compound if required by the application. Always confirm thread engagement depth and joint clamping requirements before final tightening. Follow applicable mechanical or structural codes for the specific installation context.
