Value Collection HC1X20150 Hex Cap Screw M20 X 2.50

Product Description

The VALUE COLLECTION HC1X20150 is a metric hex head cap screw manufactured from 18-8 austenitic Grade A2 stainless steel with a bright, uncoated finish. It carries a nominal thread size of M20 x 2.50 and an under-head length of 150 mm, with partial threading along the shank. The 30 mm hex drive size accommodates standard wrenches and torque equipment. Weighing approximately 1 pound, this fastener is suited for structural and mechanical assembly applications where corrosion resistance and metric dimensioning are required. It conforms to DIN 931, EN 24014, and ISO 4014 standards, making it appropriate for use in precision and code-compliant installations handled by maintenance technicians, millwrights, and mechanical contractors.

This screw is intended for use in metric-dimensioned mechanical assemblies, structural connections, and equipment fabrication or repair. Its partial threading preserves shank integrity in applications where a smooth bearing surface is needed between mating components, such as flanged joints, equipment frames, and mounting structures. The Grade A2 stainless steel construction resists oxidation and mild chemical exposure, making it a reliable choice for both indoor and outdoor installations where carbon steel fasteners would be vulnerable to corrosion.

Key Features

• 30 mm hex drive accommodates standard open-end, box-end, and socket wrenches
• Sold individually — minimum order quantity of 1

Compatibility

Designed as an OEM-style metric fastener replacement or new-installation component for mechanical assemblies, equipment frames, and structural connections requiring an M20 x 2.50 partially threaded hex head cap screw conforming to DIN 931, EN 24014, or ISO 4014 specifications.

Installation Notes

Installation is performed by qualified maintenance technicians, millwrights, or mechanical contractors using standard metric hand or power tools rated for the 30 mm hex drive. De-energize and lock out all equipment before removing or installing fasteners in live mechanical assemblies. Use appropriate thread anti-seize compound when mating stainless fasteners to stainless nut or tapped-hole assemblies to prevent galling. Verify mating thread class and material compatibility before installation.
