Detailed Engineering Specifications

Engineered for reliability and performance, this M20 x 90mm Hex Head Cap Screw is manufactured from high-strength nylon, providing exceptional corrosion resistance, electrical insulation, and a lightweight profile. With a head width of 15mm, it ensures secure engagement with standard tooling. Nylon's inherent flexibility absorbs vibration and shock, reducing stress on connected components. Its low coefficient of friction facilitates easy assembly and disassembly. This fastener is an excellent choice for applications exposed to moisture, chemicals, or where electrical conductivity must be avoided, such as in marine hardware, electrical enclosures, and chemical processing equipment.

Installation Procedure

1. Ensure the mating threads are clean and free of debris. 2. Hand-thread the M20 x 90mm Nylon Hex Head Cap Screw into the receiving component until snug. 3. Using appropriate metric tooling (e.g., a socket wrench), tighten the cap screw to the desired torque, avoiding over-tightening to prevent thread stripping or material deformation.
