# What Are Beam C-Clamps with Set Screw and Lock Nut Used For?

Supports, Clamps & Brackets · Trade series (C-clamps with locking nut) · Application guide

Typical applications, the industries that specify beam c-clamps with set screw and lock nut, and how to choose the right size, material and finish for the joint.

Beam C-Clamps with Set Screw and Lock Nuts 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 (C-clamps with locking nut), 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 (C-clamps with locking nut)
- **Category:** Supports, Clamps & Brackets

Application notes are general engineering guidance. Verify the property class and any approval requirement against your own design calculation.

Beam C-Clamps with Set Screw and Lock Nuts are used primarily for carrying or reinforcing a run of pipe, tray or rail, with separate bolts or rods making the final fixing. This page lists the industries and assemblies where they are specified, the selection criteria that matter for each application, installation practice, and the cases where a different fastener type is the correct choice. Parts are supplied to Trade series (C-clamps with locking nut).

## Typical Applications for Beam C-Clamps with Set Screw and Lock Nut

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.

## How to Specify Beam C-Clamps with Set Screw and Lock Nut for Your Application

- **Size:** Match the size to the mating part — see the dimension table below for each option.
- **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 (C-clamps with locking nut). Quoting the standard on your order guarantees interchangeable dimensions between suppliers.

## Where Beam C-Clamps with Set Screw and Lock Nut 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.

Custom manufacturing · Made to drawing

## Need a beam c-clamps with set screw and lock nut outside the standard range?

With no standard to depart from, the tolerance scheme is the specification — which dimensions are critical, and which are simply nominal. Made by milling or stamping.

Minimum order from 2,000 pieces; samples within 7 days of drawing approval.

Inside the plant

## Manufactured in our own plant

This part is cold-formed, threaded, heat-treated and finished in-house. 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.
