Precision-manufactured to tight tolerances, this M16 x 18mm Hex Head Cap Screw features a nominal diameter of M16 and a length of 18mm, with a head width of 16mm. Constructed from robust polycarbonate, it exhibits excellent tensile strength, superior impact resistance, and a high degree of chemical inertness, making it ideal for environments where corrosion or electrical conductivity are concerns. The material's inherent dielectric properties ensure safe operation in electrical assemblies. Its lightweight nature also contributes to reduced overall assembly weight without compromising structural integrity for its intended load ratings.
This component strictly adheres to the tolerances, material specifications, and quality benchmarks set by the world's leading industrial manufacturers.
1. Select the appropriate M16 mating thread or hole. 2. Insert the Hex Head Cap Screw, ensuring proper alignment. 3. Tighten using a standard M16 hex driver until snug, avoiding overtightening which can damage the polycarbonate threads.
