Feeler gauges are an essential tool for measuring small gaps and clearances in various industries, including automotive, manufacturing, and construction. They are thin, flat strips of metal with varying thicknesses that allow for precise measurement of tight spaces that cannot be easily accessed by other measuring instruments. This article will provide comprehensive information on feeler gauges, their types, uses, and best practices, equipping you with the knowledge to use them effectively and accurately.
Feeler gauges come in various types, each suited for specific applications. The most common types include:
Feeler gauges are typically made from high-quality stainless steel or hardened steel. They are available in a wide range of thicknesses, ranging from 0.0015 inches (0.038 mm) to 0.125 inches (3.18 mm). The most common thickness increments are 0.001 inches (0.025 mm) and 0.002 inches (0.051 mm).
Feeler gauges have a wide range of applications in various industries:
Using feeler gauges requires precision and attention to detail. Here is a step-by-step guide:
Feeler gauges are subject to various industry standards and regulations. Some notable standards include:
Objective: Ensure optimal ignition in an automotive engine.
Process:
Objective: Verify the correct valve operation in an internal combustion engine.
Process:
