Plastic Dial Indicator Tips
Plastic dial indicators are used for a variety of industrial and scientific applications. They are available in different designs and sizes to meet specific needs. Here are some tips to consider when using plastic dial indicators:
- Protective Case: When purchasing dial indicator tips, look for those that come in a protective plastic case. This will keep your tips organised, protected, and easy to transport. For example, the Taytools 113700 22-piece set comes in a protective plastic case, offering a variety of options for different applications.
- Thread Compatibility: Ensure that the threads on your dial indicator tips are compatible with your indicator. Some indicators use specific thread sizes, such as 4-48 or M2.5 threads. Check the specifications of your indicator before purchasing tips to ensure a proper fit.
- Crystal Care: Dial indicators have a crystal or lens that can become dirty or damaged over time. If your indicator has a plastic crystal, you can clean it by hand-polishing it with a small amount of polish on a cloth. You can also try using toothpaste, but this may be messier. Keep in mind that replacing the crystal can be difficult, as they may not be readily available and often require special tools for installation.
- Contact Point Options: Plastic-tipped contact points for dial indicators are available in various styles, such as flat, conical, or pin chuck. Choose the style that best suits your measurement needs. Plastic-tipped contact points can provide a non-marring solution for delicate workpieces.
- Digital Indicators: If you are using a digital dial indicator, ensure that you purchase compatible plastic contact points. These are designed for specific digital indicator models and may have different thread sizes or specifications compared to mechanical dial indicators.
- Storage and Handling: When storing and handling your plastic dial indicator tips, ensure that they are securely placed in their designated storage slots within the case. This prevents them from moving around and potentially getting lost or damaged. Consider adding a rubber band or an additional piece to keep the case securely closed.
By following these tips, you can effectively utilise plastic dial indicators and maintain their accuracy and longevity.

Dial Indicator with Plastic Lens
Dial indicators are precision tools used for taking accurate linear measurements and come in a variety of styles. The bezel of a dial indicator contains the graduation dial, which is a plastic lens that sits on top of the dial face. The lens is held in place by a bezel ring, which is often made of metal, such as aluminium, or plastic.
The plastic lens on a dial indicator can be removed and replaced. This may be necessary if the lens becomes scratched or cloudy, affecting the user's ability to read the dial. There are several methods for removing the bezel and lens, depending on the make and model of the dial indicator. Some require the use of a screwdriver to loosen screws, while others involve prying off the bezel with a flat-bladed screwdriver or even just by hand. In some cases, the bezel may be held in place by flanges that can be retracted by loosening a screw.
When replacing the plastic lens, it is important to ensure that the new lens is the correct size and shape. The lens must be concave so that it clears the movable dial hand. The crystal should be at least 1mm larger in diameter than the bezel opening. A crystal press is usually required to give the plastic lens its concave shape, although some indicators, such as Bestest and B&S calipers, do not require a press. When using a press, the crystal and bezel are placed in the correct orientation, with the beveled edge of the crystal facing up. As the press bends the plastic, the bezel is snapped into place.
There are also dial indicators with protective plastic cases, which house the dial indicator tips or contact points. These tips are used at the point of measurement and come in a variety of styles, including flat, conical, and pin chuck. Plastic-tipped contact points are also available, which are non-marring and suitable for use on delicate surfaces.
