Value Collection HC1X18070-010BX M18 Hex Cap Screw Din 931

Product Description

The VALUE COLLECTION HC1X18070-010BX is a metric hex head cap screw manufactured from 18-8 austenitic Grade A2 stainless steel with a bright, uncoated finish. This fastener measures M18 x 2.50 in thread size with a 70 mm length under the head and features partial threading in conformance with DIN 931. The 27 mm hex drive accommodates standard metric wrenches and sockets. At approximately 1 pound per unit, it is well suited for structural and mechanical assemblies where corrosion resistance and dimensional accuracy are required. Installation is performed by qualified tradespeople or mechanical assemblers working within metric fastener specifications.

This cap screw is designed for use in medium-to-heavy mechanical assemblies, equipment frames, pipe supports, HVAC structural components, and industrial fixtures requiring a corrosion-resistant metric fastener. Its stainless steel construction makes it a reliable choice in wet, humid, or mildly corrosive environments common in mechanical rooms, rooftop equipment installations, and process piping applications. The partial threading suits applications where a bearing shank length is needed between fastener head and thread engagement.

Key Features

• M18 x 2.50 thread size with 70 mm length under head for deep engagement applications
• Partial threading per DIN 931 standard provides an unthreaded shank section for shear load applications
• 18-8 Austenitic Grade A2 stainless steel offers strong corrosion resistance without a protective coating
• 27 mm hex drive is compatible with standard metric wrenches and impact sockets
• Bright uncoated finish maintains dimensional consistency and avoids coating buildup in threaded holes

Compatibility

Designed as a metric replacement or service fastener for equipment and assemblies requiring a DIN 931 partially threaded hex head cap screw in M18 x 2.50 thread size.

Installation Notes

Installation should be performed by a qualified mechanic or tradesperson familiar with metric fastener standards. Always verify thread engagement depth and hole condition before installation. Use a calibrated torque wrench appropriate for M18 fasteners and follow the torque specifications provided by the equipment or assembly manufacturer. Do not mix metric and imperial fasteners in the same assembly, and inspect threads for damage before reuse.
