Purpose-built for heavy-duty applications, this M22 x 22mm hex head cap screw is manufactured from high-impact polycarbonate, offering excellent chemical resistance to a broad spectrum of solvents, acids, and bases. The material's inherent dielectric properties make it ideal for environments where electrical conductivity is a concern, preventing short circuits and corrosion. With a nominal thread diameter of M22 and a length of 22mm, it provides robust fastening capabilities for structural components, equipment assembly, and enclosures in industries such as chemical processing, electrical manufacturing, and marine applications where traditional metal fasteners may degrade or pose a safety risk. The head width of 32mm ensures ample surface area for torque application.
This component strictly adheres to the tolerances, material specifications, and quality benchmarks set by the world's leading industrial manufacturers.
1. Ensure mating surfaces are clean and free of debris. 2. Hand-thread the cap screw into the designated receptacle to confirm proper alignment and avoid cross-threading. 3. Use an appropriately sized socket wrench or torque driver to tighten the cap screw to the required specification, avoiding over-tightening which can damage the polycarbonate threads.
