Key Features of Faithfull Feeler Gauges & Strips

Faithfull feeler gauges are manufactured from high-carbon steel that undergoes hardening and tempering processes to achieve optimal rigidity whilst maintaining flexibility. This careful metallurgical treatment ensures the blades can be inserted into narrow gaps without permanent deformation, yet remain stiff enough to provide accurate readings.

The dual marking system featured on Faithfull gauges displays measurements in both metric (millimetres) and imperial (thousandths of an inch) formats. This versatility proves invaluable when working with mixed specification equipment or following service manuals from different regions. Each marking is etched rather than printed, ensuring legibility throughout the tool's working life.

Individual blade lengths are optimised for accessibility in confined spaces, allowing technicians to reach gaps that would be inaccessible with bulkier measuring tools. The tapered profile of each blade facilitates insertion into tight clearances, whilst the holder design allows blades to be fanned out or used individually as required. Chrome or satin finishes on Faithfull feeler gauges provide corrosion resistance essential for tools exposed to workshop moisture and oil contamination.

Popular Faithfull Feeler Gauges & Strips

Faithfull offers feeler gauge sets in various blade configurations to suit different applications. Standard automotive sets typically include blades ranging from 0.05mm to 1.00mm (0.002" to 0.040"), covering the most common valve clearance specifications found in petrol and diesel engines. Extended range sets incorporate thicker blades up to 2.00mm for applications requiring larger gap measurements.

Individual feeler strips are available from Tooled-Up for specialists who require specific thicknesses or need to replace worn blades from existing sets. These single blades prove particularly useful for dedicated tasks where only certain measurements are regularly required, reducing bulk in mobile toolkits.

Metric and imperial dedicated sets cater to users working exclusively within one measurement system, streamlining the selection process during rapid workshop procedures. Combination sets remain the most versatile choice, accommodating the diverse range of specifications encountered in modern repair environments where equipment may originate from various international manufacturers.

Safety and Compliance

Whilst feeler gauges are inherently simple tools, proper handling remains important for personal safety and measurement accuracy. Always ensure engines are switched off and cool before measuring clearances, and never force blades into gaps as this can cause permanent deformation affecting future measurements. Wear appropriate hand protection when working around sharp engine components.

Store Faithfull feeler gauges in their protective cases when not in use to prevent damage and maintain calibration. Regular inspection of blades for signs of bending, wear, or corrosion ensures continued accuracy. Replace gauges that show visible damage or when measurements become inconsistent with known specifications. Keep gauges clean and lightly oiled to prevent rust formation in humid workshop environments.

Frequently Asked Questions

Are Faithfull feeler gauges accurate enough for professional use?

Yes, Faithfull feeler gauges are manufactured to professional tolerances and widely used throughout the automotive and engineering industries. Their hardened steel construction maintains accuracy through repeated use, making them suitable for professional workshops and trade applications.

Can I use the same feeler gauge set for both metric and imperial measurements?

Faithfull combination feeler gauge sets feature dual markings displaying both metric and imperial measurements on each blade. This allows you to work with specifications in either format without requiring separate gauge sets, making them ideal for workshops servicing diverse equipment.

How do I know which thickness feeler gauge to use?

Always consult the manufacturer's service manual for your specific equipment, which will specify the correct clearance tolerances. The appropriate feeler gauge blade should slide into the gap with slight resistance – if it moves too freely, try the next thicker blade; if it won't enter, try thinner.

Do Faithfull feeler gauges require calibration?

Feeler gauges don't require periodic calibration like electronic measuring tools, but they should be inspected regularly for wear, bending, or damage. If blades show visible deformation or measurements become inconsistent with known specifications, the gauge set should be replaced to maintain accuracy.

Can feeler gauges be used to measure threaded fastener gaps?

Whilst feeler gauges excel at measuring parallel gaps and clearances, they're not ideal for threaded applications where the measurement surface is irregular. For best results, use Faithfull feeler gauges on smooth, parallel surfaces such as valve stems, bearing clearances, and machined components where accurate gap measurement is critical.
