Fastener clamping force
WebJul 23, 2024 · Looking at the chart above, the thread column refers to the diameter of the bolt in millimeters (mm). An M3 thread bolt is 3 mm in diameter, and similarly an M5 thread bolt is 5 mm. The larger the bolt, the more torque is needed to achieve the necessary clamping force. For the sake of this article, we’ll use an M12 thread to describe bolt size. WebFeb 16, 2024 · T = F p (P/2pi +U t r t /Cos Beta + U n R n) T = Torque applied, Fp = preload in fastner. P = pitch. Ut= coeff of friction (nut and bolt threads) Beta = half angle of thread. Un = coeff of ...

WebThe preferred bolt preload for structural applications should be at least 75% of the fastener's proof load for the higher strength fasteners and as high as 90% of the proof load for permanent fasteners. To achieve the benefits of the preloading, the clamping force must be higher than the joint separation load. WebTo determine the minimum clamp force to meet this requirement, the following formula can be used: Fk = A x y/n where y is the gasket factor and other terms are as given before. Conclusions.
