Nut and Bolt Thread Checker – High Speed Steel Thread Checker Standard and Metric – Complete SAE Male Female Gauge – Accurate Measurements

I love this thing. Unfortunately so do all of my friends. Someone always ends up keeping this after they borrow it. I work in data centers and use this for determining size of nuts and bolts that I need that always seem to get lost. I also use it around the house working on my vehicles. Been spot in every time. Just thread something in or into something and hop off to the hardware store to buy what I need. Would recommend and purchase again

I always wanted one of those boards they have all over the hardware isle at the big box stores to confirm your thread pitch....this is just that much better since you can coil it up and stuff into a tool bag, drawer or wherever. I've already used it much more than I anticipated and would consider it essential for anyone with enough hardware inventory to warrant bin boxes.

In a guage size matters. The size markings aren't high contrast, also not very big, so they're not easy to read. The markings aren't engraved, so they're going to wear off and become completely unreadable.Otherwise it seems to be a good set.

Easy to read and very percision product for both sae and metric. Confirmed

Theoretically, should be handy when needed. The sizes are printed, not etched, and with heavy use I don't think they'd last.

Great for finding size and thread count of nuts and bolts. Saves time picking replacement fastners.

Does what it is meant to do but the price tag is a little high.

Nicely made!
