Professional Applications & Engineering Value

This zinc-plated steel hex twist-on nut delivers critical solutions for maintenance and production lines where speed and reliability are paramount. The coarse 1/4"-20 thread and Class 2B fit enable rapid installation while minimizing the risk of stripping, especially in high-vibration environments like conveyor systems or motor mounts. The external hex drive allows for standard wrench access, streamlining field repairs without specialized tools. Its zinc plating provides a sacrificial layer against moisture and chemicals, reducing downtime in manufacturing, automotive, or outdoor equipment applications. Engineered as a split nut variant, it accommodates slight misalignments while maintaining secure fastening, making it ideal for assembly jigs, machinery guards, and structural frameworks requiring repeated disassembly.

Specification Summary & Compliance

This nut features a 1/4"-20 coarse thread with Class 2B thread fit per ANSI/ASME B1.1 standards, ensuring dimensional accuracy and interchangeability. The external hex drive design conforms to common wrench sizes, while the right-hand thread direction follows conventional fastening practices. Physical dimensions include a 5/8" width across flats and 3/8" height for compact yet robust performance. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming the absence of restricted substances for global industrial use.
