S-90036A040 1 1/4"-7 x 3 ft. Threaded Rods

Key Features & Benefits at a Glance

• Enhanced corrosion resistance with zinc plating for extended service life in demanding industrial environments
• Reliable left-hand threading prevents loosening in counter-rotating applications, improving operational safety
• High tensile strength of 50,000 psi ensures structural integrity under heavy loads and vibration
• Class 1A thread fit provides easier assembly and disassembly while maintaining secure connections
• Full-length threading offers versatile positioning and adjustment capabilities along the entire 3-foot rod
• Rockwell B61 hardness delivers excellent durability and wear resistance for repeated use
• Comprehensive compliance with RoHS 3 and REACH standards ensures environmental and safety regulations are met

Professional Applications & Engineering Value

This left hand threaded rod addresses critical engineering challenges in applications where standard right-hand threads would naturally loosen due to rotational forces. The zinc-plated steel construction provides essential corrosion protection for industrial settings exposed to moisture and chemicals. With its UNC coarse thread spacing and Class 1A thread fit, this fully threaded rod enables quick assembly in machinery maintenance, conveyor systems, and structural frameworks where counter-clockwise rotation is present. The combination of 50,000 psi tensile strength and Rockwell B61 hardness ensures reliable performance in heavy-duty applications including automotive manufacturing, industrial equipment, and construction projects requiring left-hand fastening solutions that maintain integrity under stress and vibration.

Specification Summary & Compliance

This threaded rod features 1 1/4"-7 UNC coarse thread with Class 1A thread fit for inch system applications. Manufactured to standard specifications with left-hand thread direction and fully threaded design across the 3-foot length. The product complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across various industrial sectors while meeting international standards for hazardous substance restrictions.
