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.

Technical Specifications

Why nVent CADDY?

nVent CADDY manufactures the SN37 speed nut from electrogalvanized steel, giving installers a corrosion-resistant fastener built for repeated use on commercial and industrial job sites. As the continuation of the trusted Erico SN Series, the SN37 carries forward a design contractors already specify, now backed by nVent CADDY's manufacturing standards and consistent 3/8-Inch fit. It is a straightforward, reliable choice for electricians and mechanical trades fastening threaded rod, strut, and support hardware on commercial and industrial projects where speed and corrosion resistance both matter.

nVent CADDY SN37 – Frequently Asked Questions

1) Is the Erico SN37 the same part as the nVent CADDY SN37?
Same part number, same part. Erico became nVent CADDY, and the SN37 designation carried over, so an existing spec, BOM, or replacement stock line calling for Erico SN37 is satisfied by the nVent CADDY SN37 with no cross-reference needed.
2) Why use a speed nut instead of a standard hex nut on threaded rod?
A hex nut has to be spun from the end of the rod all the way down to the attachment point. The SN37 speed nut snaps onto 3/8 inch rod at the point you need it, which is the whole reason contractors use it when they are hanging a lot of brackets, channel, or conduit supports in sequence. Where you need a torqued, load-rated threaded connection, a standard nut is still the right call.
3) Will the SN37 speed nut hold up in a damp or corrosive industrial space?
The SN37 body is electrogalvanized steel, which resists rust and corrosion in typical indoor commercial and industrial conditions and on the job site. Electrogalvanized is a thinner zinc coating than hot dip, so for sustained outdoor exposure, wash-down areas, or coastal installs, specify a hot dip galvanized or stainless fastener instead.
4) What do electricians and mechanical contractors actually use the CADDY SN37 for?
It fastens brackets, strut channel, and hangers to 3/8 inch threaded rod on overhead support work: conduit runs, cable tray, raceway, and strut channel support systems in commercial and industrial electrical installs, both new construction and renovation.
5) Can I standardize on one speed nut across a whole conduit support job?
If the job is run on 3/8 inch rod throughout, yes. Keeping the SN37 as the single fastener line item for every bracket and hanger attachment avoids mixed hardware on the cart and in the stockroom. Mixed rod diameters on a project mean more than one SN Series size, since the SN37 only fits 3/8 inch.
6) Does the SN37 come as a single piece or in a bulk pack?
The SN37 is ordered as one model, the SN37 speed nut for 3/8 inch rod. There is no size or finish choice to make with it, so the only decision is quantity for the number of rod attachment points on your run.
