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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Good, In Spec Kit *by A***R on 20 April 2026* Everything was nice and individually wrapped.
