Kinok - 42 Nuts and Bolts Thread Tester Size & Thread Gauge, 19 Standard & 15 Metric Sizes, 8 Bit Gauge Identifier with Centimeter & Inch Ruler, Red

I love this save time ,very sturdy has standard and metric

Well made, sturdy, incredibly useful tool. So handy to identify sizes of nuts/bolts on hand for replacing parts or using pieces from the "maybe I'll need this extra bolt someday" section of the tool chest.

I is an excellent quality product. I have purchased it more then once.

I work with a lot of different sized screws, bolts, nuts, etc., and I’m always having to determine thread pitch, size and whether metric or standard. Sure, most of the time you can tell by eye or by testing on another bolt, etc., but sometimes you need to know the exact size or pitch in order to purchase more. This product allows you to determine, with surety, the sizes you need and also helps determine metric or standard, fine pitches or coarse. It’s quality made from aluminum, it’s sturdy and robust, able to withstand a lot of use and handling. There are several sizes of threaded studs, the most common ones, in which you can screw a nut on and holes sized so you can screw a bolt into. The product is labeled very well and is easy to read. I also like the color and it has two holes already drilled into it for mounting it to a wall or other area. Don’t wait like me and go without a product such as this any longer. If you work on a lot of stuff, this gauge is a must have and will definitely make your job a lot easier. It’s well worth what you pay for it!

Very sturdy. Well made. About once a month I for some reason end up with a countertop full of nuts and bolts that need to be sorted and placed back in their proper bins. This makes it so much easier.
