Value Collection HC1XX20200 M20 Hex Head Cap Screw 316 Ss

Product Description

The VALUE COLLECTION HC1XX20200 is a metric hex head cap screw sized M20 x 2.50 with a 200 mm length under head. Manufactured from Grade 316 austenitic stainless steel to the A4 material classification, this fastener delivers strong corrosion resistance in wet, marine, and chemically aggressive environments. The shank is partially threaded with a 30 mm hex drive and carries a bright, uncoated finish. It conforms to DIN 931, EN 24014, and ISO 4014 standards, making it a standard-compliant choice for precision mechanical and structural assemblies that demand dimensional consistency and material traceability.

This screw is suited for industrial, marine, food-processing, and chemical-processing applications where austenitic stainless steel is specified to resist rust and pitting. It is installed in bolted flange joints, structural frames, pump housings, pipe supports, and equipment mounting assemblies. Machinists, millwrights, pipefitters, and maintenance technicians commonly specify A4-316 fasteners when working in saltwater-exposed or sanitary environments where carbon steel hardware is not acceptable.

Key Features

• Grade 316 austenitic stainless steel (A4) for superior corrosion resistance in harsh and marine environments
• Partially threaded shank provides a bearing surface for close-tolerance bolted joints
• 30 mm hex size accepts standard open-end, box-end, and impact wrenches
• Bright uncoated finish maintains dimensional tolerances and allows torque verification without coating variables
• Manufactured to DIN 931, EN 24014, and ISO 4014 standards for dimensional and mechanical compliance

Compatibility

Designed for use in metric bolted assemblies requiring M20 x 2.50 thread engagement and conformance to DIN 931, EN 24014, or ISO 4014 dimensional standards.

Installation Notes

Installation should be performed by a qualified mechanic, millwright, or pipefitter familiar with metric fastener torque practices. Disengage power and depressurize any system before replacing structural fasteners. Use calibrated torque equipment appropriate for M20 fasteners and apply the torque value specified by the equipment or structural engineer of record. Avoid mixing stainless steel fasteners with dissimilar metals in submerged or conductive environments to limit galvanic corrosion risk.
