The price point of these pins, one cannot expect an individual inspection report on each pin. The pins have measured accurate as I can measure them and have been at stated sizes. For my home machine shop use they exceed expectations. I am working within .0005 tolerances and they are doing what I need them to do. Nicely packaged and really corrosion proofed for transit. Each pin wrapped in oil paper to protect. Fit and finish is quite awesome for the price. Very happy with my set. Looking to get next size group of pins (.251-.500) from Accusize. I hope this helps. **Q: If i want to buy only 1 set , should i buy plus or minus pin gage set ? which set experience machinists prefer ? why ? thank you so much** A: According to CCROSS: "A pin gauge set will typically consist of either plus or minus pin gauges, and based on procedure or tolerances may require both versions to determine a go no go outcome. A minus pin gauge set includes pins with a specified tolerance below the target size, allowing the pin to fit within the target dimension. Likewise, a plus pin gauge set includes pins with a specified tolerance above the target dimension, creating a no-go situation for a bore at the target dimension." So, choose the minus or the plus based on your work. **Q: What is the size of the box these pins are in?** A: Box size 4" x 5", each pin has a cap to hold onto each pin. **Q: Are all new sets coming in the new improved case?** A: As of writing, we are still in the process of upgrading the cases. So some of them might come with old cases. ## Customer Reviews ### ⭐⭐⭐⭐⭐ EXCELENTE *by A***N on 20 July 2022* EXCELENTE ### ⭐⭐⭐⭐⭐ Good product *by P***E on 24 January 2026* They are excellent for measuring small holes ### ⭐⭐⭐⭐⭐ worth every cent *by T***S on 18 January 2026* nice complete kit, well made. ## Frequently Bought Together - Accusize Industrial Tools 0.251''-0.500'', 250 Pc/Set Steel Plug Pin Gage Set, Minus, Class Zz, M2(-) - 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 0.011'' - 0.060'' Go/No Go Double End Gage Handle, 3350-0100… --- ## 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.co.uk/products/594900813-accusize-industrial-tools-0-251-0-500-250-pc-set](https://www.desertcart.co.uk/products/594900813-accusize-industrial-tools-0-251-0-500-250-pc-set) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-06-01*
