Bests & Worsts Reviews from Amazon

I hesitated to buy this thing, because while the overall review score is good, the 'Top Reviews' paint a different picture. I'm glad I bought it anyway. Wanted to respond to some of the issues other reviewers had: "Very small and there aren't any threads in the holes or the pegs that are supposed to measure nuts" If 7 inches is very small, then a lot of dudes are in trouble, myself included. It's true, the holes and pegs are not threaded. It's made of plastic, that would work maybe half a dozen times before they deformed and were no longer accurate. Instead, there is a thread gauge on the back for bolts/screws, and the pegs for nuts define thread pitch by whether or not they fit completely over it. If they can't clear the 'shoulder' of the peg halfway down, they're coarse pitch. If they can, they're fine pitch. Then just look at the conversion table printed right there on the front of the thing and boom you got your thread count. Unless you're working on NASA equipment, this will solve most any dilemma you're having with your nuts (lol) "Has no way to check the thread pitch of nuts... only their inner bore diameter." The info is right there on the unit...fit the nut to the peg, note and size and if it's coarse or fine pitch, and look at the conversion table. Metric and standard. "I need one that will define what sort of thread a given bolt happens to have, e.g., how many threads per inch? " On the back side, there's a metric and US thread pitch gauges. I'm more used to using the ones at the hardware store that are set up where you actually thread it into a hole, but this tool is easier in my opinion. The way to use it is to press the bolt on top of each gauge and try giving it a little nudge to the lateral side. If it's not a match, the bolt will kinda jitter off the plastic. When you get a match, it will 'bite' the threads and won't budge. You'll know it when you hit the sweet spot, trust me. It's easier this way because once at the hardware store I accidentally used a US bolt on the metric hole and it got locked up in there. Had to flag down an employee and have him get it out using tools. Anyway, I think this gauge is pretty useful for the DIY crowd and the price is right for most of us. It's pretty bad when misleading reviews get upvotes. This one will probably get downvoted, but I hope it helps at least one person who kept scrolling down.
