Value Collection HC3X20130-005BX M20 Hex Cap Screw

Product Description

The VALUE COLLECTION HC3X20130-005BX is a fully threaded hex head cap screw sized M20 x 2.50 with a 130 mm length under head. Manufactured from 18-8 austenitic stainless steel to Grade A2, this fastener provides strong corrosion resistance in wet, outdoor, and chemically active environments. The bright uncoated finish maintains dimensional accuracy for close-tolerance assemblies. It conforms to DIN 933, a widely recognized international standard for fully threaded hex bolts. Tradespeople and mechanical contractors reach for this grade when galvanic compatibility, sanitary requirements, or environmental exposure rules out carbon or plated steel fasteners.

This screw is suited for mechanical, structural, and equipment-mounting applications where metric fasteners and stainless material are specified. Common installations include HVAC equipment frames, pump and blower assemblies, pipe support hardware, electrical enclosures, and general trade fabrication that demands metric sizing. The M20 thread and 130 mm shank length accommodate thick flanges, through-bolted connections, and structural members where full thread engagement across the joint is required.

Key Features

• Fully threaded M20 x 2.50 metric thread for complete engagement in through-bolted joints
• 130 mm length under head suits thick flanges and structural connections
• 18-8 austenitic stainless steel, Grade A2, provides reliable corrosion resistance
• Bright uncoated finish preserves precise thread tolerances
• Conforms to DIN 933 for internationally recognized dimensional compliance
• 30 mm hex drive compatible with standard metric wrenches and sockets

Compatibility

Designed as a metric hex head cap screw for use in any M20 x 2.50 threaded application requiring DIN 933-compliant, fully threaded stainless steel fasteners.

Installation Notes

Installation is performed by mechanical, HVAC, plumbing, or electrical tradespeople using a 30 mm open-end wrench, box wrench, or socket. Ensure mating threads are clean and free of debris before assembly. When fastening stainless steel to stainless steel hardware, apply an anti-seize compound to prevent galling under torque. Follow applicable mechanical codes and equipment manufacturer torque specifications for the joint class.
