For example a 100% thread specification is only 5% stronger than a 75% thread specification but requires 3 times the torque to produce. Thread strength is not directly proportional to percent of thread. In general, tap tool life can be increased significantly by using a lower percent of thread and we suggest using values between 60% and 70% for most applications. Most tap drill charts call out only one tap drill size, and that will produce an approximate 75 percent thread.
