Professional Applications & Engineering Value

This aluminum hex threaded rod addresses critical engineering challenges in machinery assembly, prototyping, and maintenance operations. The combination of right-hand and left-hand threading on a single 12-inch rod allows for simultaneous adjustment or locking mechanisms in opposite directions—solving alignment issues in conveyor systems, clamping devices, and precision instruments. The 1/4"-28 thread size maintains consistent torque transmission and load distribution, while the hex shape prevents rotation during installation, enhancing worker safety. Made from high-grade aluminum, it resists oxidation in humid or chemical-exposed environments, making it suitable for aerospace, automotive, and electronic enclosures where weight reduction and corrosion resistance are paramount. Its compliance with RoHS and REACH standards ensures it meets global environmental regulations for industrial components.

Specification Summary & Compliance

This threaded rod features Class 2A thread tolerances for consistent fit with standard nuts and fittings. It adheres to unified thread standards (1/4"-28) for both right-hand and left-hand directions, with a total thread length of 1 3/16" on each end. The hex size is 1/4" for tool compatibility. Manufacturing complies with RoHS 3 (2015/863/EU) under exemption 6(b)-II for lead in aluminum alloys, and it is fully REACH (EC 1907/2006) compliant regarding SVHC substances as of January 2023, ensuring safe use across regulated industries.
