## Questions & Answers

**Q: Does the set come with a certificate?**
A: Yes, the gage block set includes a certificate from the manufacturer. However, for true NIST traceability and to ensure the highest level of accuracy, we recommend having the set calibrated by an accredited laboratory.

**Q: What does "Grade B" mean?**
A: Grade B refers to compliance with ASME B89.1.9-2002 standards. This grade is ideal for general-purpose shop use, offering reliable performance for a variety of measurement tasks.

**Q: Can I use a caliper to calibrate the gage blocks?**
A: No, gage blocks are more accurate than calipers. Use the gage blocks to calibrate the caliper instead. For calibrating the gage blocks, a higher-accuracy tool like a micrometer is recommended.
