Detailed Engineering Specifications

A high-performance industrial component, this M18 x 92mm hex head cap screw is manufactured from robust, UV-stabilized polycarbonate. It features a nominal thread diameter of M18 and a total length of 92mm, with a head width of 16mm for effective torque application. The inherent properties of polycarbonate provide excellent dielectric strength, chemical resistance to many common solvents and acids, and a significant weight reduction compared to metallic fasteners. This makes it ideal for applications where electrical insulation or weight savings are critical, such as in electronic enclosures, chemical processing equipment, and marine environments where corrosion is a concern.

Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Overtightening the polycarbonate screw, leading to thread stripping or head deformation.Utilize a torque wrench set to the manufacturer's recommended torque specification for polycarbonate fasteners to ensure proper clamping force without overstressing the material.
Using this screw in applications exceeding its temperature or chemical resistance limits.Consult the polycarbonate material datasheet for specific operating temperature ranges and chemical compatibility charts to confirm suitability for the intended environment.

Common Applications

  • Corrosion-sensitive environments
  • Electrical insulation requirements
  • Lightweight assembly solutions

⚠️ Engineering Warnings

  • Not suitable for high-stress structural applications requiring the tensile strength of metal fasteners.
