Professional Applications & Engineering Value

This left-hand brass hex nut delivers critical performance where standard right-hand threads would compromise safety. The brass material provides natural corrosion resistance without additional plating, making it perfect for plumbing, marine hardware, and electrical applications where galvanic corrosion is a concern. The thin profile design solves space constraints in compact assemblies while maintaining full UNC coarse thread engagement. Class 2B thread fit guarantees consistent performance in high-vibration environments, preventing costly downtime in industrial machinery, rotating equipment, and specialized mechanical systems requiring reverse-thread security.

Specification Summary & Compliance

Manufactured to precise Class 2B thread fit standards with 1 1/4"-7 UNC coarse thread specifications. This left-hand thread brass hex nut features external hex drive with dimensions of 1 7/8" width and 23/32" height. Fully compliant with REACH (EC 1907/2006) and RoHS 3 (2015/863/EU) regulations, including exemption 6(c) for lead in copper alloys, ensuring environmental responsibility and global market acceptance.
