The significant advantage is that you can easily remove any part needed for quick thread identification. This is more convenient than dealing with a bunch of gauges on cables or boards, especially if you have to check thread dimensions in narrow or hard-to-reach areas.DUAL PROCESS PRINT MARKING: To differentiate between metric and imperial sizes, we use blue for SAE (inches) and red for metric to make it easier for you to identify.EASY TO USE: Simply screw the nut or bolt into the thread gauge and check the size in just a few seconds. You no longer need to drive back and forth to the hardware and auto parts store for inspection. In addition, this nut and bolt gauge is especially good for distinguishing between similar inch and metric threads.23-inch and 21 metric: Inch sizes are blue and include 1-12, 1-8, 3/4-16, 3/4-10, 5/8-18, 5/8-11, 9/16-18 , 9/16-12, 1/2-20, 1/2-13, 7/16-20, 7/16-14, 3/8-24, 3/8-16, 5/16-24, 5 /16- 18, 1/4-28, 1/4-20, 10-32, 10-24, 8-32, 6-40, 6-32; metric sizes are red, including M3-0.5, M4-0.7, M5-0.8, M6-1.0, M7-1.0, M8-1.0, M8-1.25, M10-1.0, M10-1.25, M10-1.5, 1.25 , 1.5, 1.75, M14-1.5, M14-2.0, M16-1.5, M16-2.0, M20-1.5, M20-2.5, M24-2.0, M24-3.0.KEEP YOUR STUFF ORGANIZED: This nut and bolt organizer has 44 male/female sizes, all of which are the most commonly used sizes for daily use, which can help you quickly organize all kinds of nuts and bolts and keep them in order.
