Kindorf Spring Nut, Steel Strut Channel Hardware

Kindorf spring nuts are engineered for use with Kindorf metal framing and strut channel systems in commercial and industrial electrical installations. This family is available with thread sizes ranging from 5/16-18 through 1/2-13, sized for use in 3/4" deep channel and 1-1/2" deep channel, so installers can match the correct spring nut to the channel depth and fastener hardware on the job. Spring nuts allow bolts, threaded rod, and other hardware to be inserted directly into the open channel slot and rotated into position, eliminating the need to slide fasteners in from the channel end. This design speeds up installation of conduit supports, hangers, brackets, and other fittings onto Kindorf strut, making these spring nuts a practical addition for electricians and contractors building out support systems for conduit, cable tray, and equipment mounting throughout a facility. Constructed of steel with a Galv-Krom/Standard finish, they are built for repeated field use in demanding support-system assemblies.

Key Features

  • Thread Size Range: Available from 5/16-18 through 1/2-13 thread, matching common Kindorf channel fastener hardware for secure, code-compliant assembly.
  • Channel Depth Options: Sized for 3/4" deep channel and 1-1/2" deep channel to fit the specific Kindorf strut profile in use.
  • Spring-Loaded Design: The spring action holds the nut in place within the channel slot once inserted and rotated, allowing installers to position hardware anywhere along the channel length without threading from the end.
  • Channel-Compatible Fitting: Designed to work with Kindorf strut and framing channel, supporting conduit clamps, hanger rod, brackets, and other channel-mounted fittings.
  • Fast Field Installation: Drop-in, quarter-turn style engagement reduces installation time on support system assemblies compared to end-loaded fasteners.
  • Durable Construction: Steel construction with a Galv-Krom/Standard finish for reliable performance in support-system environments.
  • Versatile Hardware Component: Functions as a core building-block fitting for electrical, mechanical, and structural support runs using Kindorf channel systems.

Kindorf B9115/16 – Frequently Asked Questions

1) Which Kindorf spring nut do I need for 1-1/2 inch deep strut channel?
Only the 5/16-18 thread version is offered for 1-1/2 inch deep channel, under Kindorf part number B9115/16. The 3/8-16 and 1/2-13 nuts are built for 3/4 inch deep channel. Channel depth matters because the spring length has to match the inside depth of the strut for the nut to seat and hold tension against the channel lips.
2) Can I add a spring nut partway along a strut run without pulling the fasteners out the end?
That is the point of a spring nut. It drops into the open slot anywhere along the channel and rotates a quarter turn to lock, with the spring holding it in position while you start the bolt. No need to slide hardware in from the end of the strut, which is what makes them practical on conduit supports and cable tray hangers already partly built out.
3) I am hanging 1/2 inch threaded rod off strut for conduit racks. Which Kindorf nut?
The 1/2-13 spring nut, part B9121/2, which is built for 3/4 inch deep channel. If your run uses 1-1/2 inch deep strut, the only depth-matched option in this family is the 5/16-18 nut, so a heavier rod on deep channel needs a different channel nut.
4) What thread sizes do Kindorf spring nuts come in?
Three: 5/16-18, 3/8-16, and 1/2-13. Pick the one that matches the bolt or threaded rod you are hanging with, not the channel. Trade size range across the family is 5/16 inch to 1/2 inch.
5) Are Kindorf spring nuts sold individually or by the box?
They ship in packs of 100, which is how most electrical contractors buy them for a full support-system build. Each thread size and channel depth is a separate pack, so a job running both 3/8-16 and 1/2-13 hardware needs both.
6) Will these spring nuts work with other brands of strut channel?
Kindorf states these for Kindorf strut and framing channel. Channel profiles and slot openings vary between manufacturers, so match the nut to the channel depth you actually have on the job: 3/4 inch deep or 1-1/2 inch deep, which are the two depths this family covers.
7) Does a spring nut include the bolt?
No. The spring nut is the channel-side fastener only. You supply the matching bolt, threaded rod, or hanger hardware in the same thread as the nut you order (5/16-18, 3/8-16, or 1/2-13), plus any conduit clamp, bracket, or strap being mounted.
8) What are the Kindorf part numbers for each spring nut version?
Four orderable combinations: B9115/16 for 5/16-18 in 1-1/2 inch deep channel, B9125/16 for 5/16-18 in 3/4 inch deep channel, B9123/8 for 3/8-16 in 3/4 inch deep channel, and B9121/2 for 1/2-13 in 3/4 inch deep channel.
9) What material and finish are Kindorf spring nuts, and are they OK for damp indoor areas?
Steel with a Galv-Krom/Standard finish. That is a standard zinc-type protective coating suited to interior commercial and industrial support systems. For heavy outdoor exposure or corrosive process areas, a hot-dip galvanized or stainless channel nut is the usual call instead.
