Feeler gauges are tools used for measuring gaps between two surfaces or objects with precision. They are made of uniform strips of metal of precise thickness and can be a single strip or a set of strips that are hinged on the same screw or pivot pin. A feeler gauge can be adjusted to a desired measurement manually. It is inserted between the gap and moved around until resistance is encountered without forcing the surfaces apart or binding with either of the surfaces. Feeler gauges come in different types, including the wire feeler and the flat feeler, each designed to measure specific types of gaps.
What is a feeler gauge and how is it used?
The importance of precision in gap measurement
Precision in gap measurement is crucial, especially in the automotive industry and automotive repair. A feeler gauge provides precise and repeatable measurements, ensuring the continued operability of vehicles. Automotive mechanics use feeler gauges to fine-tune the gap between the contact points of older engines’ ignition systems. They also measure the gap between spark plugs, using flat feeler gauges for engines and wire feelers for spark plugs and NPT pipe threads.
Feeler gauges in the automotive industry
Feeler gauges are a staple in an auto mechanic’s tool bag. They are used to measure the precise distance between contact points in older engines or spark plugs. Feeler gauges come in different types and provide accurate and repeatable measurements, making them essential tools in the automotive industry and automotive repair.
Feeler gauges as temporary shims
In addition to gap measurement, feeler gauges can be used as temporary shims to determine the correct alignment of machines during assembly. Machines rely on shims to maintain correct alignment and not just distance. A feeler gauge can be used as a temporary shim to determine the correct alignment so that the machine is assembled properly.
Different types of feeler gauges and their uses
There are different types of feeler gauges, including flat feeler gauges and wire feeler gauges, each designed to measure specific types of gaps. Flat feeler gauges are used for measuring gaps in engines, while wire feelers are used for measuring gaps between spark plugs and NPT pipe threads. Graduated feeler gauges, which have measurements indicated along the surface or circumference of the tool, can be gradually inserted into the gap until resistance is felt, and the measurement can be taken.
Graduated feeler gauges: a versatile measuring tool
Aside from the common flat and wire feeler gauges, graduated feeler gauges are versatile measuring tools that can cater to different applications. They can be used for precise gap measurements in various industries, such as automotive, carpentry, and dentistry. Carpenters use nails of specific thickness to space planks before nailing or screwing them, while doctors use dental floss to determine the ideal spacing between teeth or crowns.
In conclusion, feeler gauges are essential tools for precise gap measurement. They provide accurate and repeatable measurements and come in different types to cater to different applications. Whether you are an auto mechanic, carpenter, or dentist, feeler gauges are versatile tools that can help you achieve accurate results in your work.
