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 ### ⭐⭐⭐⭐⭐ Review *by A***N on 20 July 2022* EXCELENTE ### ⭐⭐⭐⭐ Review *by Q***O on 2 July 2025* This is a very good set of gage blocks and work as intended. ### ⭐⭐⭐⭐⭐ Review *by G***E on 16 January 2026* For the price these work just fine. ## Frequently Bought Together - Accusize Industrial Tools Precision 81-Piece Steel Gauge Block Set, Grade B Accuracy, Corrosion-Resistant, P900-S581 - Accusize Industrial Tools - 190 Pc Precision Minus Class ZZ Pin Gauge Set, 0.061" to 0.250", 2" Length, Heat Treated, 60-62 RC, with Aluminum Case, M1(-) A - Accusize Industrial Tools 0.251''-0.500'', 250 Pc/Set Steel Plug Pin Gage Set, Minus, Class Zz, M2(-) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.ar/products/239147496-accusize-81-pcs-set-steel-gage-block-set-grade-b](https://www.desertcart.com.ar/products/239147496-accusize-81-pcs-set-steel-gage-block-set-grade-b) --- *Product available on Desertcart Argentina* *Store origin: AR* *Last updated: 2026-05-20*
