37Z23 - ESAB Bronze Retaining Nut 1.38-18 Thread 1.005 ID

Technical Specifications of the ESAB 37Z23 Retaining Nut

The ESAB 37Z23 Retaining Nut is a precision-engineered component designed for industrial oxy-fuel cutting equipment. Manufactured to strict tolerances, this nut features a specific 1.38-18 thread pitch, ensuring a secure mechanical connection within the torch assembly. The internal diameter is machined to exactly 1.005 inches, providing the necessary clearance for internal torch components while maintaining structural rigidity.

Material selection is critical for components exposed to the extreme thermal cycles of oxy-fuel cutting. This retaining nut is constructed from high-quality bronze (BZ), a material chosen for its superior thermal conductivity and resistance to oxidation. Unlike ferrous alternatives, bronze is less likely to seize or gall on the threads after prolonged exposure to heat, facilitating easier maintenance and disassembly. This durability ensures that the torch head remains securely fastened, which is vital for maintaining gas seal integrity and cutting precision.

This part serves as a direct replacement for damaged or worn retaining nuts on compatible ESAB and Victor-style machine torches. Using genuine OEM-spec parts like the 37Z23 guarantees that the equipment remains within its original safety and performance specifications. It is an essential spare part for maintenance departments looking to minimize downtime and ensure the longevity of their cutting automation hardware.
