Value Collection HC3X18150 Hex Head Cap Screw M18 X 2.50

Product Description

The VALUE COLLECTION HC3X18150 is a fully threaded metric hex head cap screw designed for fastening applications that require corrosion resistance and dimensional precision. Manufactured from 18-8 austenitic stainless steel to Grade A2, it delivers reliable performance in wet, chemical-exposed, or outdoor environments. The screw measures M18 x 2.50 thread pitch with a 150 mm length under head and a 27 mm hex drive. It conforms to DIN 933, EN 24017, and ISO 4017 standards, making it a drop-in fit for metric-spec assemblies across mechanical, structural, and industrial applications. Plumbers, pipefitters, HVAC technicians, and general tradespeople regularly use Grade A2 fasteners wherever stainless hardware is spec-required.

This cap screw is suited for metric fastening tasks in both residential and commercial settings. Typical uses include equipment mounting, pipe flange connections, bracket assembly, and general structural fastening where a corrosion-resistant stainless fastener is required. The fully threaded shank allows engagement along the entire 150 mm length, providing consistent clamping force in through-bolt and tapped-hole applications. Its bright, uncoated finish is appropriate for food-service equipment, marine environments, chemical processing skids, and any assembly governed by a metric fastener standard.

Key Features

• Conforms to DIN 933, EN 24017, and ISO 4017 dimensional standards
• Sold individually — single-piece minimum order quantity

Compatibility

Designed as an OEM-style replacement or new-installation fastener for metric-spec assemblies requiring M18 x 2.50 fully threaded hex head cap screws per DIN 933, EN 24017, and ISO 4017.

Installation Notes

Installation should be performed by a qualified tradesperson following applicable mechanical or structural codes. Verify that the mating thread is clean and free of debris before installation. Use a calibrated torque wrench sized for a 27 mm hex drive and apply torque to the fastener specification required by the assembly — do not over-torque stainless fasteners, as galling can occur. Anti-seize compound rated for stainless steel is recommended for high-temperature or high-humidity applications to prevent thread seizure.
