Tube End 3/8-24 LH 3/4in x .058in

The ALLSTAR PERFORMANCE Tube End 3/8-24 Left-Hand 3/4in x .058in (SKU ALL 22513) is a precision weld-on threaded tube fitting engineered for custom fabrication and race car assembly. This left-hand female thread connector is machined from chromoly steel, delivering the strength and durability required in high-stress welded tube applications where vibration, thermal cycling, and sustained load are primary concerns.

The 3/8-24 left-hand thread pattern accommodates rod end applications and custom linkage systems where standard right-hand threading would create orientation conflicts. The 3/4-inch tube diameter fits mid-range frame and suspension tubing common in fabricated race car builds and off-road vehicle construction. The 0.058-inch wall thickness specification is critical—it indicates the exact tube wall this fitting is designed to mate with, ensuring proper weld-bead geometry and structural integrity at the joint. Chromoly construction provides superior strength-to-weight compared to mild steel, a requirement in competition environments where frame reliability directly impacts safety and performance.

Custom fabricators, race shop mechanics, and off-road builders rely on precision tube ends to create repeatable, code-compliant welded assemblies. Whether designing custom suspension geometry, building transmission tunnels, or fabricating rollcage systems, matching the exact thread specification and wall thickness prevents fitment gaps, welding defects, and post-fabrication modifications. This single-piece unit arrives ready to weld, reducing lead time on custom frame projects.

ALLSTAR PERFORMANCE is recognized in the racing and fabrication community for precision fastening solutions that meet the demanding tolerances of competition-grade assembly. The natural chromoly finish requires post-weld painting or coating to prevent corrosion, a standard practice in fabrication shops.
