Electro Galvanized Steel Channel Nuts

When electro galvanized is the right choice

Electro galvanized steel is the economical standard for strut in dry, indoor, and protected environments, from mechanical rooms and commercial ceilings to interior equipment mounting. The zinc plating resists rust in those conditions at a lower cost than stainless, and the full range of styles, standard spring, without spring, top lock, and short spring, covers most framing needs. For wet, outdoor, or coastal exposure where the zinc would eventually corrode, step up to 316 stainless.

Channel nut styles in electro galvanized

• Standard spring: a spring holds the nut for easy one-hand setting.
• Without spring: economical plain nut positioned by hand.
• Top lock spring: grooved teeth bite the channel for extra grip.
• Short spring: shorter spring for tight or shallow channel runs.

Common applications for electro galvanized channel nuts

• Indoor strut framing and supports
• Commercial pipe, conduit, and cable tray hangers
• Mechanical, electrical, and HVAC mounting
• Dry, protected equipment racking
