Supports, Clamps & Brackets · Trade series (strut channel brackets and fittings) · Application guide Typical applications, the industries that specify channel brackets and fittings, and how to choose the right size, material and finish for the joint. Channel Brackets and Fittings are used for carrying or reinforcing a run of pipe, tray or rail, with separate bolts or rods making the final fixing. They are manufactured to Trade series (strut channel brackets and fittings), and selection is driven by the nominal size, the fit and tolerance the assembly requires, and the service environment. - **Primary duty:** Carrying or reinforcing a run of pipe, tray or rail, with separate bolts or rods making the final fixing - **Governing standard:** Trade series (strut channel brackets and fittings) - **Nominal size range:** 90-degree angle bracket to 90-degree angle bracket - **Category:** Supports, Clamps & Brackets Application notes are general engineering guidance. Verify the property class and any approval requirement against your own design calculation. ![What Are Channel Brackets and Fittings Used For? application image](https://engineeringhardware.com/wp-content/uploads/2026/09/Channel-Brackets-And-Fittings.webp) Channel Brackets and Fittings (Trade series (strut channel brackets and fittings)) are specified where the joint requires carrying or reinforcing a run of pipe, tray or rail, with separate bolts or rods making the final fixing. The sections below cover the typical end-uses by industry, the size and material decisions for each, assembly practice, and the applications this fastener type is not suited to. Stocked across roughly 90 mm to 90 mm, they cover heavy and structural work. ## Typical Applications for Channel Brackets and Fittings The most common settings where these are specified: - **General machine building:** fastening covers, brackets, motors and sub-assemblies on production equipment. - **Maintenance & repair (MRO):** a stocked size for servicing existing plant where the original fastener spec must be matched. - **Fabrication & metalwork:** bench and on-site assembly of steel frames, enclosures and weldments.

This product spans 90 mm–90 mm; check the full table below for the exact dimensions of each size. - **Material:** Choose the material and finish for the service environment — plated steel for general use, stainless for corrosion resistance. - **Environment:** For damp, coastal or chemical exposure prefer A4/316 stainless or a suitable coating; indoors, plated steel or A2 is usually sufficient. - **Standard:** This product is supplied to Trade series (strut channel brackets and fittings). Quoting the standard on your order guarantees interchangeable dimensions between suppliers. ## Where Channel Brackets and Fittings Are Not the Right Choice Match the fastener to the load, environment and whether the joint must be reopened; the wrong class or style is the usual cause of joint failure.

The stages below are where its class and finish are actually decided. 1. ![Wire rod feeding into a cold heading machine](https://engineeringhardware.com/wp-content/uploads/2026/08/09-wire-rod-feed-cold-heading-machine.webp) 01 **Cold heading** Wire rod is drawn to size and cold-formed into blanks. Forming rather than cutting keeps the grain flow continuous around the head, which is where a bolt is most likely to fail. Head dimensions and under-head radius checked at set-up and per shift. 2. ![Thread rolling machine producing bolt threads](https://engineeringhardware.com/wp-content/uploads/2026/08/03-thread-rolling-machine-bolt-production.webp) 02 **Thread rolling** Threads are rolled between hardened dies rather than cut. Rolled threads are stronger in fatigue than cut threads and hold pitch and flank angle far more consistently across a batch. Go / no-go ring gauges to ISO 965 tolerance class 6g. 3. ![Baskets of bolts staged for heat treatment](https://engineeringhardware.com/wp-content/uploads/2026/08/05-heat-treatment-baskets-black-bolts.webp) 03 **Heat treatment** Quench-and-temper brings carbon and alloy steel to the property class ordered — 8.8, 10.9 or 12.9 — with the furnace charge tracked so a finished lot can be traced back to it. Core hardness and tensile tested per lot to ISO 898-1. 4. ![Zinc plated bolts in a treatment basket](https://engineeringhardware.com/wp-content/uploads/2026/08/23-zinc-plated-bolts-treatment-basket.webp) 04 **Surface treatment** Zinc, zinc-nickel, hot-dip galvanizing, black oxide, phosphate and Dacromet, selected against the service environment rather than against the price list. Coating thickness and neutral salt spray hours to ISO 9227. ## Frequently Asked Questions ### Which industries use Channel Brackets and Fittings? They are commonly specified in general machine building, maintenance & repair (mro) and fabrication & metalwork, among other sectors. ### How do I choose the right size of Channel Brackets and Fittings?
