However, how do you apply torque tightening correctly? In this post, we will discuss the basics of torque tightening and some of the theory behind the process. What is Torque Tightening. Torque tightening is the application of torque to a nut allowing a bolt to be pre-loaded. Pre-load in a bolt is an axial force that creates tension. As every
Typically only 10% to 15% of the overall torque is actually used to tighten the bolt, the rest is used to overcome friction in the threads and on the contact face that is being rotated (nut face or
Anti-loosening performance of pitch difference nut is controlled by α and n. Larger thread number n and smaller α is better for fatigue and anti-loosening. In this paper,
The preload indicator bolt assembly is a fastener that achieves the desired preload effect by simply tightening the preload nut within a specified range without additional measuring tools. The inner washer is a critical component in this assembly, with its outer diameter and height serving as crucial design parameters. In this paper
Proper nut tightening ensures seal integrity, prevents leaks, and safeguards power generation systems against fluid ingress, contamination, or environmental damage.

Typically only 10% to 15% of the overall torque is actually used to tighten the bolt, the rest is used to overcome friction in the threads and on the contact face that is being rotated (nut face or bolt head). This is illustrated in the
The fatigue life is also improved largely by α = 15 μm coupled with ρ = 2 ρ 0. In a word, both the fatigue limit and the fatigue life of bolt nut connections can be significantly improved by enlarging the root radius and introducing an appropriate pitch difference at the same time . Fig. D1.
Hard-lock Nut composed of two nuts with eccentric structure has witnessed the success of Japanese Shinkansen for several decades and is widely used worldwide . To improve fatigue strength, mainly two methods are available; one is using special surface treatment and the other is modifying thread geometry.
This is partly because during T < 0, the nut is untightened by a manual torque wrench causing relatively larger errors included. Second, there is a manufacturing error in the pitch as discussed in the authors’ previous paper .
The molybdenum disulfide grease spray M o S 2 is used on the thread surface as lubricating oil; then, friction coefficient in thread surface μs and the friction coefficient in bearing surface μw are also measured by using the device during the nut tightening.
During the nut untightening, the torque is measured manually by using a torque wrench and reading the clamping force recorded on the device at the same time. As shown in Table 1, the yield stress of the bolt material SCM435 is 800 MPa with the bolt cross-sectional area of 84.3 mm 2.
A plastic tightening method used in the automotive industries is known as a good method for preventing fatigue of bolts , , , . However, FEM analysis showed that anti-loosening properties cannot be improved by the plastic tightening although the scatter of the initial clamping force can be reduced .
