Purpose-built for heavy-duty applications, this M20 x 38mm Hex Head Cap Screw is manufactured from premium 316 stainless steel, renowned for its superior corrosion resistance in marine, chemical, and outdoor environments. The M20 nominal size, 38mm length, and 32mm head width provide substantial bearing surface and torque capability, ideal for high-stress connections. Its robust design ensures reliable performance under extreme conditions, preventing premature failure and maintaining structural integrity. This fastener is a critical component for ensuring the longevity and safety of complex assemblies.
This component strictly adheres to the tolerances, material specifications, and quality benchmarks set by the world's leading industrial manufacturers.
1. Clean both the threaded hole and the screw threads to remove any debris or contaminants. 2. Apply a small amount of anti-seize compound to the threads if operating in potentially corrosive environments to facilitate future disassembly. 3. Insert the screw into the designated fastening point and hand-tighten initially to ensure proper alignment. Use an appropriate socket wrench or torque wrench set to the manufacturer's recommended torque specification for the M20 size to achieve a secure connection without over-tightening.
