Detailed Engineering Specifications

Built to exacting engineering tolerances, this M22 x 90mm polycarbonate hex head cap screw is manufactured from a high-performance polymer renowned for its excellent chemical inertness, high impact strength, and superior dielectric properties. The material's inherent resistance to a wide range of acids, bases, and solvents makes it an ideal choice for applications in corrosive or chemically active environments where traditional metal fasteners would degrade. Furthermore, its non-conductive nature is crucial for electrical insulation applications, preventing short circuits and ensuring safety in sensitive assemblies. The precise M22 thread pitch and 90mm length, coupled with a 12mm hex head width, facilitate secure and consistent fastening in various light-duty structural and equipment assembly scenarios.
