Installation Tips

• Ensure the mating bolt or stud is clean and free of debris for smooth threading.
• Apply a light thread lubricant or anti-seize compound when using carbon steel variants in high-moisture environments.
• Hand-start the cap nut to avoid cross-threading, then tighten with a 7/16″ wrench or socket to the recommended torque.
• If reusing cap nuts on critical assemblies, inspect threads for wear and replace if necessary to maintain safe performance.
