3/4-16 LH Tube End - 1-1/2in x .120in

The 3/4-16 LH Tube End is a weld-on threaded component engineered for chromoly tubing fabrication and custom frame assembly. This left-hand female threaded tube end (part number RE1030FL) is designed to accommodate 1-1/2-inch diameter tubing with a 0.120-inch wall thickness, making it essential for applications requiring precise thread engagement in chromoly construction.

The 3/4-16 LH specification delivers a metric-compatible thread pitch in left-hand configuration, critical for applications where reverse-rotation safety or directional assembly logic demands counter-clockwise threading. Chromoly material provides excellent weldability and strength characteristics for both MIG and TIG welding processes, while the natural finish allows for post-fabrication surface treatment or coating application. The 0.120-inch wall specification ensures sufficient material mass to support reliable thread formation without excessive material removal during threading operations.

This tube end serves fabricators, race builders, and custom frame manufacturers who require precision threaded connections in chromoly structures. Whether assembling steering components, suspension linkages, or custom structural frames, the left-hand female thread configuration ensures positive directional security in high-vibration environments. The compact dimensions (2.05 x 1.75 x 3.65 inches) facilitate integration into tightly spaced assemblies, while the 0.69-pound weight remains practical for applications where mass efficiency matters.

Tube ends like this are foundational components in custom fabrication work, offering a proven alternative to threaded inserts or heavier welded boss designs. The weld-on design eliminates the need for complex drilling and tapping operations post-fabrication, reducing labor time and improving thread consistency across production runs.
