Professional Applications & Engineering Value
This tube end weld nut delivers critical engineering solutions where standard fasteners fail. The 4130 alloy steel construction provides exceptional strength-to-weight ratio, making it ideal for aerospace frames, heavy-duty automotive suspensions, and industrial hydraulic systems. The left-hand UNF fine threading specifically addresses vibration-induced loosening in rotating machinery and directional systems. With Class 2B thread fit precision, it eliminates play in high-stress connections while the full 2-inch thread length ensures maximum load distribution. Engineered for 1 3/4" OD tubing applications, this weld nut solves alignment and stress concentration issues in tubular structures where weld integrity is paramount.
Specification Summary & Compliance
Manufactured to precise UNF fine thread specifications with Class 2B thread fit tolerance ensuring consistent engagement. The 1 1/4"-12 left-hand thread pattern maintains ISO-compliant dimensional accuracy throughout the 2-inch thread length. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental standards guarantees material safety and regulatory acceptance for global industrial applications.
