nVent CADDY SN37 Electrogalvanized Steel Speed Nut, 3/8-Inch

nVent CADDY SN37 Electrogalvanized Steel Speed Nut, 3/8-Inch

The nVent CADDY SN37 is an electrogalvanized steel speed nut sized for 3/8-Inch threaded rod, built for fast, secure fastening in strut, conduit, and cable support assemblies. Formerly sold under the Erico name and now part of the nVent CADDY SN Series, the SN37 combines a proven speed-nut design with a corrosion-resistant electrogalvanized finish suited for demanding commercial and industrial environments. Electricians and mechanical contractors use this speed nut to attach brackets, channel, and hangers to threaded rod quickly, without running a standard nut the full length of the rod. Because it is sized specifically for 3/8-Inch threaded rod, the SN37 helps installers keep hardware standardized across a job when multiple supports and hangers are being fastened in sequence.

Key Features

• Trade Size: Engineered for 3/8-Inch threaded rod, giving installers a precise, secure fit without oversizing hardware.
• Durable Construction: Electrogalvanized steel body resists corrosion and rust, supporting long service life across typical job-site and indoor commercial conditions.
• Speed Nut Design: SN Series speed-nut configuration snaps onto 3/8-Inch threaded rod for quick placement, cutting installation time compared to running a standard hex nut down the full length of the rod.
• Legacy Erico Compatibility: Continues the Erico SN37 part number under the nVent CADDY brand, so it drops into existing specifications, BOMs, and replacement stock without a cross-reference headache.
• nVent CADDY Manufacturing: Produced by nVent CADDY for consistent dimensional fit and reliable holding performance on strut, conduit, and cable support systems.
