Thread Checker, 30 Nut and Bolt Thread Checker, Bolt Size and Thread Gauge 15 Standard & 15 Metric, Bolt Size Finder, Wall-Mountable Bolt Thread Identifier Gauge with Inch & CM Ruler

The quality of this item surprised me, just feeling the weight of the box told me this item was built to last! I tried a few standard and metric nuts and bolts on it and they all threaded in/on smoothly, this was a very pleasent surprise for such a low cost item. It's solidy built, does what its supposed to do; it even looks good, and should last a lifetime.

Perfect for the Home Mechanic who needs to order random screws from Amazon.Aluminium made, Sturdy

What a surprise! This is all I wanted and more. It's sturdy and well made. Heavy duty and has non-skid feet at the corners. Easy to read sizes and very accurate. Two small holes at one end allow it to hang for storage. Plus it looks great on the wall.My hardware is a jumble and looking for the correct nut or bolt is time consuming. This will help me sort and organize by size and thread pitch. Money well spent.

This device is well made and easy to use. The construction is rugged and it is surprisingly heavy even though the base is aluminum.There are two rows of male and female fixtures. The left side is metric and the right side is Imperial. I found it was easiest to start with the male fixture for sorting both nuts and bolts. To sort nuts just try threading the nut onto each male fixture to see which one is a match. For bolts and screws it is easiest to start by visually checking which male piece is a near match by aligning the threads as shown in the photo. Then a final check can be made by screwing the bolt into the corresponding female opening. This is a fast way to match bolts, and it minimizes the risk of cross threading a bolt into the softer aluminum section.This worked great for sorting my junk drawer of miscellaneous nuts and bolts.

These are nice! The case and the pieces themselves are quality.Do I need these? No, but they will save me time and money from having to drive to the nearest hardware store to find the correct size. More than half the time, Home Depot doesn’t have it and I end up having to order the part on Amazon anyway and having this would give me the comfort and accuracy to find THE nut, bolt, and thread from the convenience of my garage.To have this set of tools is what every DIY person needs. I could have used this two weeks ago looking for an adapter thread and bolt size on my transmission cooler when I was switch to AN lines. Of course I had to have the gambit of sizes on hand only to find out I had none of them. It took me an extra two days just to find the correct size. Once this tool arrive I confirmed the size I needed, I indeed already put in. The point it, it would have been out at ease sooner. I got this just for giggles and now I regret not having it in my garage to begin with.From one DIY to another, get one. You won’t regret it and at these low prices, now is a good time to get a set.

Looks to be good quality Looks better than the one at the hardware store

This bolt thread finder is a total lifesaver in the garage. I can’t tell you how many times I’ve wasted time guessing thread sizes — not anymore! It’s super easy to use, accurate, and saves a ton of frustration. I love how everything is clearly labeled and well-organized.If you work with fasteners regularly, this is a must-have. I seriously love it — one of those tools you didn’t know you needed until you have it!

Very good qualityEase to use
