5 Causes of Loose Bolts – and 5 Ways to Prevent Them

A pressurized bolted flange joint assembly begins to leak, creating a safety hazard. A rotor with its blades separates from the nacelle and spins off a wind turbine, crashing to the ground. Under constant vibration from the engine of an ocean freighter, loose bolts on a large piece of mining equipment work their way off […]

What is the Nut Factor and How Does it Affect Torque?

When you tighten a bolt in a bolted joint, you use a twisting force, called torque. Torque is related to bolt tightness, but many additional factors – such as friction – combined into a single “nut factor” can have a significant impact on the relationship of torque to the tightness of the bolted joint. Here’s […]
