A193 B7/A320 L7 Fully Threaded Studs with Corrosion Resistance PTFE Coating
Our premium fastener assemblies combine high-performance A193 B7 or A320 L7 fully threaded studs with heavy hex nuts, all featuring a specialized PTFE (Polytetrafluoroethylene) coating for superior corrosion protection. These complete fastening solutions are engineered for demanding industrial environments where reliability, strength, and resistance to harsh conditions are critical. Manufactured from high-grade alloy steels, these stud and nut assemblies undergo precision processing to ensure consistent performance, while the PTFE coating adds an extra layer of defense against corrosion, chemicals, and extreme temperatures. This combination creates a fastening system designed to maintain integrity in the most challenging applications.
