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.
