Before buying clamping levers for your industrial devices, you need to understand the differences in features, components, and accessories. In general, though, a cam lever or cam clamp is a quick-action fastening device that you can use to loosen your workpieces.
Wondering how they work? This article explains the mechanism of clamping levers, their different clamping elements, and other features you should know.

A clamp lever is mainly used in industrial contexts to tighten and loosen screws without other tools. It comes in handy when you need to work in tight spaces on heavy-duty equipment. Clamp levers consist of a threaded stud, serration, lever part, and spring. They also come in male and female thread models.
From the outside, you'd notice how the adjustable hand lever releases the threaded serration engagement when you pull it up. Curious about what goes on behind the scene? To understand this, you need to know how the clamp level structure and mechanism work.
First, the lever and threaded serration are connected, and they rotate at the same time when they encounter some degree of clamping force. Then, when you pull the lever, it releases the threaded serration engagement and returns it to its original state.
Clamping mounts help you adjust the axial and radial positions of mating components. In addition, it connects the different parts of the lever without any obstructions.
Depending on the type of clamping lever, adjustable clamping lever, or clamping handle, you can use one of these mount-types:
The pull handle can be made from plastic, stainless steel, cast iron, or zinc die-cast. On the other hand, the external thread is made from steel, stainless steel, and similar materials. Each material has its unique features.
For example, plastic levers are lightweight, stainless steel is corrosion-resistant and steel is strong. Therefore, it would be best to consider your individual needs before choosing a lever handle or crank handle made from a particular material.
Adjustable levers or clamping levers have a semi-ratcheting feature useful for tensioning and clamping on machines, devices, and different types of mechanisms. They consist of a nut or bolt fixed into a wrench.
To move the lever into its best clamping position, you should pull the handle up and make the necessary adjustments. The hand lever goes back to its original position once it is released.
A clamping knob is an integral part of an adjustable lever. You should think of them as revolving handles that provide a firm grip or some degree of secure control through clamping elements such as texturing, knurling, lobes, or wings. The design of clamping knobs allows them to comfortably grasp and adjust applications that require turning or medium torque.
The most common types of knobs for clamping levers are T-shaped. They allow for powerful gripping, especially in small spaces, and you can adjust them easily. Clamping lever knobs are made from different materials like phenolic, glass-fiber reinforced technopolymer, thermoplastic, and duroplast.
As the name suggests, a control lever or lever fitting is used to regulate devices, including clamps. For example, with a control lever, you can easily adjust your clamping lever using a mechanical linkage that matches the lever movement.
Control levers are attached to the end of a control cable. This allows it to mechanically enhance the applied force needed to operate a control cable. You can also adjust the tension in a line or multiply the clamping power that the cable delivers.
A control head comprises foot pedal controls, panel-mounted units, and multiple cable control units. Depending on the type, you may also find handles, pedals, and mounting brackets in your control lever.
Using clamp levers can improve your work efficiency significantly while reducing your screw operation space. Therefore, these levers are one of the essential tools needed for workshops.
If you're looking to turn out quality work consistently, you should consider purchasing one or more clamp lever applications.
