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

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.

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.

Great design, metric and standard both bolt match and nut match.It's a hefty tool, made from quality materials and heavier than I expected. it will live in our garage on a wall board!I was able to use it to match the screws and quickly found what size they were. simple to use the left is side is metric, and the right side is standard.It's a bit larger than I expected, but that allows for more sizes of screws/nuts to match

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

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

great product that any weekend mechanic could benefit from not having to go to the hardware store to measure bolt/nut sizes. It's a lot sturdier than I thought and easily hangs on my pegboard so I always know where it is.

I love having my own thread measuring tool! This one is perfect for my needs.
