Description：

【Detachable Thread Gauges in Case】The biggest highlight is that you can feel free to take out any wanted pieces to do a fast thread identification. More handy to use than all thread checks on a cable or on board, which means that when you have to do thread size check on some equipment or on some hard to reach area, you do not need to spin a bulky gauge set around.

【Laser-Etched Sizes on Both Sides】To better help distinguish metric and inch sizes, we make metric and standard items in different colors respectively ( blue for SAE, red for metric). Moreover, we improve thread checker set with each thread size gauge etched in double sides( front and back side), which avoid the hassle that you have to spin a round to check the etched size on the thread gauges.

【Quick Identification and Time Saver】Just screw the nut or bolt onto thread gauge. Only take seconds to check the size. With thread checker standard and metric, you can easily and quickly check correct size of the nuts & bolts and replace the snapped, loose, rusted or old ones at home or garage by yourself, no need to run towards hardware store for size check any more, greatly improving your work efficiency.
