Adjustable handles are commonly used to adjust machinery, fixtures and tooling systems. They support manual adjustments via turning. Once installed, you can grab and turn the handle to adjust the machinery to which it’s connected. Hex head handles, however, feature an additional mechanism for making adjustments. Here’s everything you need to know about hex head handles.
What Are Hex Head Handles?
Hex head handles are adjustable handles with a hexagonal drive recess. Like most adjustable handles, they are used to adjust machinery, fixtures and tooling systems. The difference is that only hex head handles feature a hexagonal drive recess.
Other types of adjustable handles lack a hexagonal drive recess. Instead, they typically feature a flat top or a button top, the latter of which allows for quick and easy disengagement.
Hhex head handles have the following features:
- Threaded insert
- Handle
- Hexagonal drive recess
Why Hex Head Handles Have a Hexagonal Drive Recess
The hexagonal drive recess allows for an alternative method of tightening and loosening. You can still make adjustments by turning the handle itself. Alternatively, though, you can use the hexagonal drive recess.
Placing a hex key inside the hexagonal drive recess and turning it will tighten or loosen the machinery to which the handle is connected. Turning it clockwise will tighten it, whereas turning it counterclockwise will loosen it (assuming it uses right-hand threads).
When to Use a Hex Head Handle
You may want to use a hex head handle for applications requiring high torque. There’s only so much torque you can apply when turning a handle by hand. A simple solution is to use a hex head handle. Placing a hex key inside the recess and turning it will allow you to apply additional torque.
Another instance in which a hex head handle can prove useful is in applications involving excessive vibrations. If the machinery vibrates, you may struggle to apply the necessary torque by hand. With a hex head handle, you can use a hex key for stronger, more precise torque.
One of the biggest advantages of using a hex head handle is that it saves space. In small spaces, a standard adjustable handle may not support a full revolution. You may be able to turn it partially, but you won’t be able to turn the handle all the way around. In scenarios such as this, you can use a hex head handle to make adjustments.
