Engineered for reliability and performance, this M16 x 43mm hex head cap screw features a robust 304 stainless steel construction, providing excellent tensile strength and superior resistance to rust and corrosion. The specified head width of 29mm ensures compatibility with standard tooling for secure installation. Its metric thread pitch (M16) and 43mm length make it suitable for medium-duty to heavy-duty applications where environmental factors like moisture, chemicals, or saltwater are present, demanding enduring fastener integrity. The inherent properties of 304 stainless steel, including its austenitic structure, contribute to its non-magnetic nature and suitability across a broad temperature range.
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. Insert the cap screw into the intended fastening point. 3. Tighten the cap screw using an appropriate wrench or socket to the specified torque value.
