Review on Inch and Metric Fastener Thread Checker: Bolt Your Worries Away! by Jason Ortiz

This is a good idea I wanted to make for myself by buying any size screw and bolt and then attaching them to the board so I can test at my leisure how in hardware stores. This idea will work, but if you have a hole and can't lift it up to screw it into a thread on the board, you're stuck. bring the whole piece onto the board. Pros: * The price is high (but the cheapest option I've found for a similar item). * It saves me time - lots of time! Instead of driving an infinite number of unknown screws into unknown holes, I usually identify a hole of the right size in a matter of seconds. After a few tries, I can then use the opposite end to find the right screw. Greatness instantly and confidently. Disadvantages: * The sizes are indicated in each case, but hardly. The stamp is white, not embossed, so will wear out soon I'm sure.* They are incomplete ie. not all sizes here, but the most common. I haven't had any problems yet, but we'll see over time. By doing this, I can simply purchase the missing size nut and bolt to complete my current set for much less than purchasing larger, more complete versions of that set. *The wire they are attached to is strong and I needed bolt cutters to remove it. As already mentioned, driving a screw/bolt into the sample holes is very easy and not a problem at all. But when you need to screw one end of the screw into an unfamiliar hole, you can't do more than half a turn before you do some crazy maneuvers to get the whole line spinning repeatedly. Uncomfortable. Solution: * I cut mine and re-strung with 4 much smaller lines: 1 small line for SAE and 1 small line for metric. Then I did the same for the two lines with the big end. MUCH more comfortable, and unlikely to grab the wrong line very often. (The jump in size is pretty noticeable about halfway through each type, so you can see it with the naked eye.) Wildly easier to screw into an unfamiliar hole, no hassle. I can always trace them later if the weaker line breaks. I used grommets to protect the threads and then put all 4 in separate bags for extra protection as I tend to use pieces with smaller ends. In general this is a good solution, but with some problems. The price was significantly lower than the other options, so for me the adjustments are worth it and the time saved is worth the money spent if, like me, you estimate screw sizes very often.
