Feeler Gauges: A Handy Tool for Precision Measurements

Precision measurements hinge on accuracy, making it paramount for individuals in various fields like professional mechanics, engineers, and even DIY enthusiasts. Possessing the correct set of tools is indispensable in this regard. Among these tools, the feeler gauge, though often overlooked, plays a pivotal role in attaining precise measurements.

What is a Feeler Gauge?

A feeler gauge comprises a collection of slender metal or plastic strips designed for assessing the space or distance between two objects. It encompasses a set of blades with differing thicknesses, each clearly labeled with its respective measurement. Typically, these blades are fastened together at a single end, creating a convenient and user-friendly instrument.

How Does a Feeler Gauge Work?

Feeler gauges operate based on the concept of "go/no-go" measurements. Users choose the suitable blade from the set and try to insert it into the gap being assessed. If the blade smoothly fits without encountering any resistance, it signifies that the gap falls within the desired range. Conversely, if the blade cannot be inserted or seems excessively loose, it signals that the gap is either too narrow or too wide.

Feeler Gauge Types

1. Wire-Type Feeler Gauges
   A wire-type feeler gauge differs from the standard shim setup. Instead of consisting of a series of graded metal leaves or blades, the wire feeler gauge comprises a series of inflexible metal wires. These wires are calibrated to specific thicknesses and are typically bent at a right angle. Wire-type feeler gauges are commonly used to measure spark plug gaps and are sometimes referred to as spark plug gap gauges.
2. Blade Feeler Gauges
   Among the various types of gap gauges available online, blade feeler gauges are perhaps the most commonly encountered. They typically include a range of graded, flattened metal shims or leaves that can be folded in or out of a central case or sheath. These blades can be easily fanned out from the central case to select and access the desired one. If a single strip becomes damaged or breaks, you can purchase an individual replacement strip of the same thickness.
3. Thin Feeler Gauges
   All feeler gauges are inherently thin because their purpose is to fit into and measure narrow gaps that are often too tight for most other conventional measuring tools, such as tape measures. It is relatively uncommon to find sets that include blades thicker than approximately 5mm at the upper limit, although such sets do exist. Most individuals who purchase feeler gauges for mechanical or engineering tasks are primarily concerned with measuring much smaller gaps. Thin feeler gauges can be graded down to thicknesses as slim as 0.02mm or even less. The measurements for individual blades may be provided in either metric or imperial units, or both. When shopping online for gap gauges in the UK, make sure to check that your chosen product displays the appropriate measurement units for your needs.
4. Angled Feeler Gauges
   Angled feeler gauges are equipped with tips that are bent at a slight angle compared to the rest of the blade. This design is advantageous for accessing hard-to-reach gaps where it may not be possible to insert a standard gap gauge straight enough to obtain an accurate measurement of the gap's width. These are also known as offset feeler gauges.
5. Feeler Gauge Sets
   It is more common to begin by purchasing a feeler gauge set and then replace individual blades if they become damaged or worn over time. A set of multiple blades or leaves allows you to test various strips of different thicknesses in the gap you are attempting to measure. This typically simplifies the process of determining the gap size through a straightforward comparison and elimination method.
6. Plastic Feeler Gauges
   A plastic feeler gauge is one in which the blades are constructed from plastic material instead of metal. Although less physically durable than most metal counterparts, plastic feeler gauges can be highly valuable in specific situations and applications. They do not corrode, are non-conductive, and therefore do not generate sparks. Additionally, they will not scratch any of the components you are measuring gaps between. Plastic versions are often color-coded to facilitate differentiation between specific shim thicknesses.
