Frequently asked questions
What accuracy do I need from feeler gauges?
Choose accuracy and resolution based on the tolerance you must verify. A display with many digits is not automatically accurate enough for tight-tolerance work.
Digital or mechanical?
Digital tools are fast to read and convert units. Mechanical vernier/dial tools avoid batteries and can be excellent when maintained and read correctly.
How do I get repeatable measurements?
Clean the measuring faces and part, use consistent measuring force, align the tool correctly and allow temperature-sensitive precision work to stabilize.
Do these tools need calibration?
For casual comparative work, periodic checks against known standards may suffice. Quality-control or tolerance verification can require traceable calibration.
Can I measure a hot part accurately?
Temperature changes dimensions and can affect the instrument. Precision measurements should be made under appropriate, stable conditions.
What damages precision measuring tools most often?
Drops, chips on measuring faces, excessive clamping force, moisture and using the instrument as a marking or clamping tool.
Should I buy a larger measurement range?
Only if needed. Smaller-range precision tools can be easier to handle and may offer better suitability for the dimensions you measure most.
