Value Collection HC3X20100 Hex Head Cap Screw M20 X 2.50

Product Description

The VALUE COLLECTION HC3X20100 is a metric hex head cap screw manufactured from 18-8 austenitic Grade A2 stainless steel with a bright, uncoated finish. It features an M20 x 2.50 mm thread profile, a 100 mm length under head, and is fully threaded along its entire shank. The 30 mm hex drive size accommodates standard metric wrenches and sockets. This fastener meets DIN 933, EN 24017, and ISO 4017 dimensional and mechanical standards. It is suited for structural and mechanical assembly applications where corrosion resistance and metric dimensioning are required. Installation is performed by maintenance technicians, millwrights, and mechanical contractors.

This hex head cap screw is used in general industrial, commercial, and mechanical assembly applications where metric fasteners and corrosion-resistant stainless steel construction are specified. Fully threaded geometry makes it well suited for through-bolted joints and connections requiring full thread engagement across the clamped material stack. It is commonly installed in equipment frames, pipe supports, enclosures, and machinery where exposure to moisture or chemicals demands stainless hardware.

• Meets DIN 933, EN 24017, and ISO 4017 dimensional standards

Compatibility

Designed as a metric hex head cap screw for use in any application requiring an M20 x 2.50 mm fully threaded fastener conforming to DIN 933, EN 24017, or ISO 4017 specifications.

Installation Notes

Installation is performed with a standard 30 mm metric open-end, box, or socket wrench. Ensure mating threads are clean and free of debris before installation. When assembling stainless steel fasteners, apply an appropriate anti-seize compound to prevent galling, which can occur with austenitic stainless threads under torque. Follow project engineering specifications or applicable mechanical codes for required torque values and joint preload.
