Engineered for reliability and performance, this M21x109mm Nylon Hex Head Cap Screw features a robust M21 thread diameter and a nominal length of 109mm. The hex head boasts a controlled width of 27mm, ensuring optimal torque application with standard tooling. Manufactured from high-grade Nylon, it exhibits excellent chemical resistance to a broad spectrum of solvents, oils, and alkalis, along with superior electrical insulation properties and a high strength-to-weight ratio. Its operating temperature range is typically -40°C to 100°C, making it suitable for applications where temperature fluctuations are common. The inherent flexibility of Nylon also contributes to vibration dampening.
This component strictly adheres to the tolerances, material specifications, and quality benchmarks set by the world's leading industrial manufacturers.
1. Select appropriate metric wrench or socket for the 27mm hex head. 2. Ensure mating threads are clean and free from debris. 3. Thread the screw into the receiving component, applying consistent torque until snug. Avoid overtightening to prevent thread stripping or material deformation.
