It is especially well suited for distinguishing between similar inch and metric threads. Our unique Thread Identifiers (aka thread checkers) are available in Metric, English Standard, and a combo of Metric and English Standard. For your convenience we provide extra-long wire rope for those hard to reach places, as well as loops on each end for convenient hanging. Inch Thread Identifiers contain nut and bolt sizes of 1-64, 1-72, 2-56, 2-64, 3-48, 3-56, 4-40, 4-48, 5-40Metric Thread Identifiers contain nut and bolt sizes of M1.2x0.25, M1.6x0.35, M1.6x0.20, M1.8x0.35, M2.0x0.40, M2.0x0.40, M2.0x0.25, M2.5x0.45, M2.5x0.35, M3.0x0.50, M3.0x0.35, M3.5x0.60, M3.5x0.35. Review: Good deal; good tool - I've had some small threaded parts that I've been scratching my head over for a month, when I finally decided to spring for these "thread identifiers". Glad I did; they solved my problem in less than 30 seconds. You can find larger sized thread testers all over the place, but these tiny sizes are hard to come by. Couple of points: * The female testers don't spin around, as some users have said. That means if you need to test the threads on a stationary rod, you will have to rotate the whole tester chain to get it threaded on the rod. But I wasn't expecting anything else, and it's not a big deal -- the whole chain is barely a foot long and very easy to manipulate. * Some reviewers have claimed that the size labels on the testers are adhesive stickers. Well, I don't know what they might have gotten, but the set I received has the numbers laser-etched into the metal: easy to read and look like they'll last a good long time. Overall, I'm glad I bought these, and would buy again if needed. Review: For Small sizes machine screws - Most of the thread checkers skip on the really small size. This one covers for the missing sizes. Looks well made. I also have the middle sizes thread checkers from the same brand and it is serving me well. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B071ZF2XJ8 | | Additional Features | Lightweight | | Age Range Description | All | | Best Sellers Rank | #146,327 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #135 in Thread Gauges | | Brand | Raofuo | | Brand Name | Raofuo | | Built-In Media | User Manual | | Color | Black | | Connectivity Technology | Wired | | Control Method | Remote | | Customer Reviews | 4.7 out of 5 stars 89 Reviews | | Ear Placement | Over Ear | | Earpiece Shape | over-ear cups | | Enclosure Material | Metal | | Form Factor | Over Ear | | Global Trade Identification Number | 00844788054486 | | Headphone Folding Features | Over Ear | | Headphone Jack | 3.5 mm Jack | | Headphones Ear Placement | Over Ear | | Headphones Jack | 3.5 mm Jack | | Item Weight | 5.76 ounces | | Manufacturer | Innovative Components | | Model Name | 844788054486 | | Model Number | 844788054486 | | Noise Control | None | | Number of Items | 1 | | UPC | 844788054486 | | Unit Count | 1 Count | | Water Resistance Level | Waterproof | ## Product Details - **Brand:** Raofuo - **Included Components:** User Manual - **Age Range (Description):** All - **Item Weight:** 0.36 Pounds - **Unit Count:** 1 Count ## Images ![Thread Detective/Thread Identifier Mini Metric and SAE/Inch Set - Image 1](https://m.media-amazon.com/images/I/81SYXtXypwL.jpg) ![Thread Detective/Thread Identifier Mini Metric and SAE/Inch Set - Image 2](https://m.media-amazon.com/images/I/71oCmyaJK3L.jpg) ![Thread Detective/Thread Identifier Mini Metric and SAE/Inch Set - Image 3](https://m.media-amazon.com/images/I/713N8iKi1dL.jpg) ![Thread Detective/Thread Identifier Mini Metric and SAE/Inch Set - Image 4](https://m.media-amazon.com/images/I/71Nci7H8GvL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Good deal; good tool *by D***H on August 2, 2019* I've had some small threaded parts that I've been scratching my head over for a month, when I finally decided to spring for these "thread identifiers".

This one covers for the missing sizes. Looks well made. I also have the middle sizes thread checkers from the same brand and it is serving me well. ### ⭐⭐⭐⭐⭐ Got a Loose Screw? *by T***N on February 17, 2020* I bought these to sort a couple bagfuls of bolts and nuts that accumulated over the years. I also use them to determine what the thread size/pitch is for every odd repair project that comes along that I can't eyeball. If you work with hardware, get a set of these. They are indispensable when it comes to accurately determining what a bolt/nut is, without going back and forth to your supplies multiple times. Highly recommended. Make sure you get a small and large sized set and don't loan them out, they will never come back! --- ## 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.pl/products/59545606-thread-detective-thread-identifier-mini-metric-and-sae-inch-set](https://www.desertcart.pl/products/59545606-thread-detective-thread-identifier-mini-metric-and-sae-inch-set) --- *Product available on Desertcart Poland* *Store origin: PL* *Last updated: 2026-05-18*
