This stainless steel feeler gauge provides precise thickness and slotsize measurement for reliable clearance checks in automotive and mechanical work. Its simple construction and fine workmanship make it easy to use, while the rustresistant material ensures durability in workshop environments. Key features and benefits Material: stainless steel for corrosion resistance and long service life. Precision: precision measurements for accurate size and slot size checks. Design: simple structure with fine workmanship for straightforward operation. Versatility: suitable for measuring clearances across various components and systems. Reliability: robust construction supports repeated use in demanding workshop conditions. What it measures and how it helps Measures thickness and slot size to determine clearances accurately. Used to check gaps and clearances on ignition points, valve tappets, spark plug gaps, piston ring end gaps, and brake band clearances, among other smallgap applications. Supports quick verification against engineering or service specifications, aiding proper assembly and adjustment. Applications and use scenarios Scenario 1: Before engine maintenance, verify spark plug gap to specification to ensure proper ignition performance. Scenario 2: Check valve tappet clearance or ignition points gap to maintain correct timing and valve operation. Scenario 3: Measure piston ring end gaps or brake band clearance during engine or brake service to confirm proper fit. How to use (brief guidance) Step 1: Select the appropriate gauge thickness for the required clearance. Step 2: Insert the gauge between the two contacting surfaces with light pressure. Step 3: Read the thickness and compare it to the service specification; repeat as needed for accuracy. Step 4: After use, clean the gauge and store it in a protected place to prevent corrosion. Notes Designed for general purpose use in automotive and mechanical settings. Maintain cleanliness of contact surfaces for accurate readings. Do not bend or excessively deform the gauge to preserve accuracy.
