Length of Thread b

Reference only

①,All bolts of nominal lengths equal to or shorter than b plus a length equivalent to 2.5 times the thread pitch for sizes up to and including 1 in., and 3.5 times the thread pitch for sizes larger than 1 in. shall be threaded for full length. The unthreaded length under the head and shall not exceed the length of 2.5 times the thread pitch for sizes up to and including 1 in. and 3.5 times the thread pitch for sizes larger than 1 in.
②,b is a reference dimension tntended for calculation purposes only. When screw length L ≤ 6 in，b=2d+0.25；when L＞6 in，b=2d+0.5 。
