Professional Applications & Engineering Value
Engineered for industrial applications requiring lightweight corrosion resistance, these 6061 aluminum hex nuts with UNC coarse threads solve critical challenges in assembly-intensive environments. The 1/4"-20 thread size provides optimal grip strength while the standard external hex drive enables rapid installation with common wrenching tools. Particularly valuable in aerospace, automotive, and electronics enclosures where weight reduction matters, these ASME B18.2.2 compliant nuts maintain structural integrity while preventing galvanic corrosion when paired with aluminum components. The Class 2B thread fit ensures consistent clamping force distribution, making them ideal for vibration-prone applications where loose fasteners could compromise system safety.
Specification Summary & Compliance
Manufactured to ASME B18.2.2 specifications with Class 2B thread tolerances for precision fit. Features 1/4"-20 UNC coarse threads with right-hand orientation and standard 7/16" width across flats. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring suitability for global industrial supply chains and restricted substance-free applications.
