Concept explainers

Metrology of Screw Threads

Screw threads are a series of ridges having the profile of a helix. This helix profile runs continuously along the length of a uniform solid or a hollow bar of a circular cross-section at periodic intervals. These helix ridges are also formed over a conical bar. These continuous helical ridges are termed threads.

RB&W11 recommends turn-of-nut from snug fit to preload as follows: 1/3 turn for bolt grips of 1-4 diameters, 1/2 turn for bolt grips 4-8 diameters, and 2/3 turn for grips of 8-12 diameters. These recommendations are for structural steel fabrication (permanent joints), producing preloads of 100 percent of proof strength and beyond. Machinery fabricators with fatigue loadings and possible joint disassembly have much smaller turns-of-nut. The RB&W recommendation enters the nonlinear plastic deformation zone. The figure shows a cross section of a grade 25 cast-iron pressure vessel, with a torque factor K of 0.09. Use Eq. (8-27) to estimate the torque necessary to establish the desired preload given that preload F;= 14.4 kip, bolt stiffness kb = 5.21 x 106 lbf/in, number of threads N=11, and material stiffness km = 8.95 × 106 lbf/in. in-11 UNCX 2 in grade 5 finished hex head bolt in in 162 No. 25 CI Determine the torque necessary to establish the desired preload and the turn of the nut in…

1. Name some uses of threads. Give an example of each. NOTE: Screw Thread – A screw thread may be visualized as a flexible form, like a piece of string that has been wrapped around a cylinder, or the sides of the cylindrical hole, at a uniform rate of advance, producing a form known as a helix. It may also be considered as a raised form produced on the outside of a cylinder, or on the inside walls of a cylindrical hole after a thread-cutting operation has been completed.

Required information For a bolted assembly with six bolts, the stiffness of each bolt is kb 2 Mibf/in and the stiffness of the members is km = 13 Mlbf/in per bolt. An external load of 80 kips is applied to the entire joint. Assume the load is equally distributed to all the bolts. It has been determined to use 1/2 in-13 UNC grade 8 bolts with rolled threads. It is desired to find the range of torque that a mechanic could apply to initially preload the bolts without expecting failure once the joint is loaded. Assume a torque coefficient of K = 0.2. NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part. Determine the maximum bolt preload that can be applied without exceeding the proof strength of the bolts once the load is applied. The maximum bolt preload that can be applied is Ibf.
