Saves so much time organizing. *by C***R on July 10, 2025* This one surprised me. It’s a great product. Come with both coarse and fine + SEA and Metric. Bought it to put my bolt organizer to use and it’s 10x easier than using a ruler or caliper or 4$ size board from Lowe’s. The product comes in a decent case that has 2 layers of foam (top and bottom) the pieces include some really small one but they fit in the foam tightly and won’t shake out. All pieces are actually made out of metal which surprised me. ## Frequently Bought Together - 44pcs Nut and Bolt Thread Checker, 23 Inch & 21 Metric Box Set Thread Gauge, Thread Checker Standard and Metric Suitable for Size Checker of Bolts or Nuts in Narrow Areas - ChgImposs Metric & Imperial & US Screw Gauge SAE Whitworth 55 Degree & Metric 60 Degree & & US 60 Degree Thread Pitch Gauge for Industrial Measurement - Grip Thread Pitch Gauge MM & SAE Markings - Measures Counts from .25 to 5.5mm and 4 to 42 SAE - 60 Degree Thread Profiles and Locking Devices - Garage, Workshop, Home --- ## 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.id/products/601341060-44pcs-nut-and-bolt-thread-checker-23-inch-and-21](https://www.desertcart.id/products/601341060-44pcs-nut-and-bolt-thread-checker-23-inch-and-21) --- *Product available on Desertcart Indonesia* *Store origin: ID* *Last updated: 2026-05-09*
