Value Collection HC1X20220 Hex Head Cap Screw M20 X 2.50

Product Description

The VALUE COLLECTION HC1X20220 is a metric hex head cap screw designed for heavy-duty fastening applications requiring corrosion-resistant hardware. Manufactured from 18-8 austenitic Grade A2 stainless steel with a bright uncoated finish, this fastener offers reliable resistance to rust and chemical exposure in demanding environments. The screw features an M20 x 2.50 thread size with a 220 mm length under the head and a 30 mm hex drive. It is partially threaded per DIN 931, EN 24014, and ISO 4014 standards, making it suitable for applications where a grip length on the shank is required. Licensed tradespeople and maintenance professionals working with metric hardware will find this fastener meets recognized international standards.

This hex head cap screw is suited for use in industrial, mechanical, and structural assembly applications where metric fasteners are specified. The partially threaded shank allows for a clamping zone free of thread engagement, which is common in bolted joint designs involving thicker materials or precise load distribution. It is appropriate for equipment assembly, machinery maintenance, and fabrication work across manufacturing, facilities maintenance, and industrial service trades.

Installation Notes

Installation should be performed by a qualified mechanic or maintenance technician familiar with metric fastener specifications. Always confirm thread engagement depth and joint design before installation. Use a calibrated torque wrench when tightening to the values specified by the equipment manufacturer or applicable engineering standards. Stainless steel fasteners are susceptible to galling during installation; apply an appropriate anti-seize compound when required by the application.
