Purpose-built for heavy-duty applications, this M18 x 48mm Hex Head Cap Screw features a robust polycarbonate construction, offering exceptional chemical resistance and a high impact strength rating. The nominal diameter is M18, with an overall length of 48mm and a head width of 20mm, providing ample surface area for secure fastening. This material choice is crucial for environments exposed to corrosive substances or subject to significant shock, outperforming traditional metal fasteners in such conditions. Its non-conductive properties also make it suitable for electrical applications where conductivity is a concern.
This component strictly adheres to the tolerances, material specifications, and quality benchmarks set by the world's leading industrial manufacturers.
1. Ensure the mating threads are clean and free of debris. 2. Thread the M18 Polycarbonate Hex Head Cap Screw into the receiving component by hand for the initial turns to prevent cross-threading. 3. Utilize an appropriate wrench or socket to tighten the screw to the required torque, avoiding over-tightening which can damage the polycarbonate material.
