Total length of engaged thread is about 0.5625in. According to the 7th edition of Roark's, the transverse shear (due to make up torque) is the dominant force in the threads, due to the fact that the thread is essentially an extremely short beam with a great depth. Thanks for the information Cockroach and Hydtools, however, I am still a littleconfusedworried. Have questions? American National Standard Stub Acme Threads:- This American National Standard ASME/ANSI B1.8-1988 (R2001) provides a Stub Acme screw thread for those unusual applications where, due to mechanical or metallurgical considerations, a coarsepitch thread of shallow depth is required. If a fit having less backlash is required, the tolerances and allowances for general purpose thread Class 3G or 4G of ASME/ ANSI B1.5 may be used to determine the limiting . Our manufacturing employees are our greatest asset - always providing products with precision and products that exceed expectations. take the recommended 1/4 turn to make up at recommended barrel torque.
