64Pcs Detachable Thread Checker Kit: Nut and bolt thread checker kit includes 36 standard & 28 metric sizes, every thread checker is inserted into a black box with a foam storage rack. When you do a thread check in a narrow area or go to the hardware store to buy a missing nut or bolt, you can easily take out the thread checker and quickly identify the thread size you need, which is more convenient than wire or plate thread checker.
Materials and Workmanship: Our thread checker standard and metric kits are made of high quality aluminum. To better help distinguish standard and metric sizes, we use blue for standard size and red for metric size, each thread gauge surface text is processed by laser engraving technology, which is friction-resistant, legible and long-lasting.
