Clamping knobs offer a simple and effective way to make adjustments. They are industrial knobs used in adjustment applications that require turning or clamping. Once installed, you can turn a clamping knob to adjust a machine or piece of equipment. With so many different options, however, you might be wondering which one to choose.
Material
You should consider the material when choosing a clamping knob. Some of them are made of different materials than others. Phenolic is a popular material in which clamping knobs are made. A type of thermoplastic, phenolic is strong, durable, lightweight and long-lasting.
Style
Clamping knobs are available in different styles. Some of them are smooth, whereas others are textured or “knurled.” There are also star-style clamping knobs. Star knobs feature multiple lobes to create the appearance of a star. With that said, the number of lobes they have may vary. Some star knobs only have three lobes, whereas others have up to eight lobes.
Size
Don’t ignore the size when choosing a clamping knob. Some clamping knobs are small and compact, whereas others are larger and bulky. What size should you get exactly? You’ll need to consider the machine or equipment with which you intend to use it. Only then will you be able to choose a clamping knob in the correct size.
Refer to the diameter and height to determine the size of a clamping knob. Keep in mind, though, that larger clamping knobs are oftentimes easier to grip and turn, making them a popular choice for applications that require moderate torque.
Mounting Type
Something else to consider when choosing a clamping knob is the mounting type. Like with other industrial knobs, clamping knobs are available in two primary mounting types: stud and tapped. They are used in the same adjustment applications, but they require different methods to install.
The stud mounting type features a threaded stud. The tapped mounting type, on the other hand, features a threaded hole. You should choose the mounting type that’s compatible with the machine or equipment with which you intend to use the clamping knob. If the machine or equipment has a threaded hole, you should choose a tapped clamping knob. If it has a threaded stud, you should choose a studded clamping knob.
In Conclusion
Choosing the right clamping knob is important. By considering the material, style, size and mounting type, you’ll be able to choose the perfect clamping knob for your adjustment application.
