Specified by design engineers worldwide, this M23 x 49mm Hex Head Cap Screw boasts a nominal diameter of M23 and a length of 49mm, with a head width of 20mm. Constructed from high-performance polycarbonate, it exhibits superior tensile strength, excellent dielectric properties, and remarkable resistance to a broad spectrum of chemicals and environmental factors. Its lightweight yet durable nature makes it ideal for applications requiring non-magnetic and non-conductive fastening solutions, including electronics, medical equipment, and corrosive industrial settings.
This component strictly adheres to the tolerances, material specifications, and quality benchmarks set by the world's leading industrial manufacturers.
1. Ensure the receiving threaded hole is clean and free of debris. 2. Thread the polycarbonate hex head cap screw by hand for the initial engagement to prevent cross-threading. 3. Tighten the screw using an appropriate wrench or socket on the hex head, applying gradual torque until the desired clamping force is achieved, avoiding over-tightening.
