OEMTOOLS Combination Tune-Up Feeler Gauge 25023 Metric & SAE Set

Description

Product Overview

The OEMTOOLS 25023 Combination Tune‑Up Feeler Gauge is engineered for professionals who demand precision and durability in a compact tool. This 18‑piece set combines metric and SAE blades, providing coverage from 0.006 inch (0.152 mm) up to 0.045 inch (1.143 mm). Each blade is forged from hardened, tempered steel or brass, delivering a measurement accuracy of ±0.001 inch. The gauge measures just 2.3 inches thick, making it easy to store in a toolbox or pocket without sacrificing performance. Its clear, laser‑etched markings ensure quick identification of each blade, reducing the time spent searching for the right size during critical maintenance procedures.

Usage

Designed for a wide range of applications, this feeler gauge excels in automotive engine tuning, HVAC system servicing, and general industrial equipment maintenance. Mechanics use it to set valve clearances, adjust spark plug gaps, and verify bearing tolerances. HVAC technicians rely on the precise blade sizes to calibrate blower motor shafts and check refrigerant line clearances. In manufacturing environments, the gauge assists quality‑control inspectors in verifying dimensional specifications on machined parts. Its robust construction allows use in harsh workshop conditions, while the compact size enables field technicians to carry it on‑site for rapid diagnostics.

The gauge’s dual‑system design eliminates the need for separate metric and SAE sets, streamlining tool inventories and reducing the risk of using the wrong blade size. Whether you are a seasoned mechanic, an HVAC specialist, or a maintenance engineer, the OEMTOOLS feeler gauge provides the confidence that comes from accurate, repeatable measurements.

FAQ

What is the measurement range of this feeler gauge?

The gauge includes blades ranging from 0.006 inch (0.152 mm) up to 0.045 inch (1.143 mm), covering the most common clearances needed for automotive, HVAC, and industrial equipment.

Can I use the gauge for both metric and SAE measurements?

Yes, the set is a true combination gauge. Each blade is marked with both metric and SAE dimensions, allowing you to switch seamlessly between the two systems without needing separate tools.

How does the accuracy of ±0.001 inch affect my work?

That level of accuracy ensures that even the smallest clearance adjustments are made correctly, which is critical for engine valve timing, spark plug gaps, and bearing fits. It helps prevent over‑adjustment that could lead to premature wear or performance loss.

Is the gauge suitable for use in harsh workshop environments?

Absolutely. The hardened steel and brass construction resists corrosion and wear, while the sturdy case protects the blades from impact and debris, making it ideal for busy, dirty shop floors.

What warranty does OEMTOOLS provide for this product?

OEMTOOLS offers a limited warranty that covers manufacturing defects. If you encounter any issues, you can contact their customer service team for replacement parts or a full replacement, ensuring long‑term reliability.
