Square nuts are essential for C-channel and strut channel mounting systems. JLHY's square nuts are designed to sit squarely in channels, providing secure threaded connection without the nut spinning or falling into the profile. The square profile prevents rotation when tightening — the flat sides lock the nut in position for one-person installation.

Produced in carbon steel with zinc plating for general use and in stainless steel A4 for outdoor and marine environments. Standard channel nuts come with a spring for automatic alignment. Grip-tooth variants hold the nut in position before the bolt is installed for pre-assembly applications.

Used throughout electrical installations, HVAC ductwork, structural support framing, signage systems, and industrial storage racking. JLHY supplies channel nuts to electrical contractors, mechanical engineers, and racking system manufacturers worldwide.
