WebIn general, a screw can hold 80-100 pounds. Several factors can impact on the amount of weight the screw can hold. This includes the length of the screw, the type of thread, the quality of the screw, the way it was inserted, and the type of forces that will be acting on it. Let’s take a closer look at each of these factors so you can be sure ... WebMinimum = 0.033P for all pitches. See table for maximum. When using L1 gauges to check threads, the thread is within permissible tolerance if the ring gauge face, or plug gauge notch, is +/- 1 turn from being flush with the end of the thread. Example designation: 3/8 - 18 NPT. where: 3/8 = nominal pipe size. 18 = number of threads per inch.
