Heavy-Duty M6-M12 Spring Nuts for Strut Channel Systems
Our M6-M12 Spring Nuts, also known as Channel Nuts, are essential components for securing fittings, electrical panels, and pipe clamps within standard 41mm series strut channels. Designed with a high-tension spring, these nuts stay securely in place during installation, allowing for easy adjustment along the length of the channel without slipping.
Whether you are working on Solar Mounting Structures or HVAC Support Systems, our precision-engineered spring nuts ensure a vibration-resistant connection. We provide a full range of sizes including M6, M8, M10, and M12, manufactured to withstand high load-bearing requirements in demanding industrial environments.
- Self-Locking Design: The spring provides constant pressure, holding the nut in place for hands-free bolt installation.
- Multiple Spring Lengths: We offer Long Spring for 41x41mm channels and Short Spring for 41x21mm shallow channels.
- Corrosion Resistance: Available in Hot Dip Galvanized (HDG) for outdoor use and SS316 for marine-grade applications.
- Toothed Grooves: The nut edges feature serrated grooves that bite into the channel flange for maximum grip and slip resistance.
Our Spring Nut series is tested for pull-out and slip resistance to ensure safety in overhead installations.
| Thread Size | Nut Thickness (mm) | Spring Length | Material |
|---|---|---|---|
| M6 | 6.0 mm | Long/Short | Carbon Steel/SS304 |
| M8 | 6.0 / 8.0 mm | Long/Short | Carbon Steel/SS304 |
| M10 | 8.0 / 9.0 mm | Long/Short | Carbon Steel/SS316 |
| M12 | 9.0 / 12.0 mm | Long/Short | Carbon Steel/SS316 |
- Insert the Spring Nut into the open side of the strut channel.
- Rotate the nut 90 degrees until the serrated grooves align with the channel’s intake flange.
- Position the nut at the desired location; the spring will hold it against the channel lips.
- Place the bracket or fitting over the nut and secure with an M8 or M10 bolt.
Q: Can I use M10 Spring Nuts in a 41×21 channel?
A: Yes, but you must use the Short Spring version. Long springs are specifically designed for 41×41 or deeper channels.
Q: What is the benefit of a Zinc-Plated finish?
A: Electro-zinc plating (Clear or Yellow) provides a cost-effective rust protection layer suitable for indoor dry environments.
