Flaring the Ends The appropriate single, bubble or double flare can be formed, using a good quality flaring tool such as the 007 flaring tool. The preferred method of testing nuts follows that of bolts in adoption of a test in full size to measure the load which the nut will carry without. A bolt usually has a flat tip and is built to work with a matching nut, and is engineered to be torqued by the nut. Hexagon Nut and Bolt Sizes. As long as the shank is not smaller than the thread root, it won't be any weaker than the thread, and therefore overall strength will be unaffected, but it is much more flexible (less stiff) than the original nominal size shank. In most cases, you can use a nut or bolt to check the threads. It's a bit more accurate than that, everything from the diameter of the bolt without the thread, with the thread, pitch of the thread and even the shape of the thread is defined to a tolerance. Wish I had this thread gauge years ago!!.
