Specified by design engineers worldwide, this M21 x 112mm Nylon Hex Head Cap Screw is manufactured from high-strength, impact-resistant polyamide. It features a nominal thread diameter of M21, a total length of 112mm, and a nominal head width of 13mm, conforming to industry standards for secure and reliable fastening. The inherent properties of nylon provide excellent resistance to a wide range of chemicals, solvents, and environmental factors, making it suitable for applications where metal fasteners would degrade or interfere with sensitive equipment. Its lightweight nature further enhances its utility in weight-sensitive assemblies.
This component strictly adheres to the tolerances, material specifications, and quality benchmarks set by the world's leading industrial manufacturers.
1. Ensure the threaded hole or nut is clean and free of debris. 2. Insert the Hex Head Cap Screw into the designated fastening point. 3. Tighten using an appropriate wrench or socket to the specified torque, avoiding over-tightening which can strip the nylon threads.
