How to Avoid Bolt Failure

“We sometimes underestimate the importance of little things,” wrote Charles W. Chestnutt in 1901.

Why is a torque wrench company opening a blog post about bolt failure with a quote by a turn-of-the-century author?

Because bolts are often the smallest elements of a design, but that does not make them unimportant. When bolts fail, they can do so in ways that are very catastrophic, and very public. Just ask the commuters who saw the steel rods on Oakland, California’s Bay Bridge snap in 2013.

The Basics of Bolted Joints in Wind Turbines

Wind turbines are held together with bolted joints that are under constant attack from vibration, fatigue, corrosion and bolt relaxation.

Windpower Engineering magazine lists a few things professionals in the wind industry – especially those in the market for new wind turbine torque tools – should know about tightening and tensioning.

Bolt Tightening and Quality Control

We’ve used this blog to talk about quality control before, but today we’re going to approach this topic from a new angle: quality control as it relates to bolt tightening.

As the website Bolt Science puts it:

“It is no longer sufficient just to run a nut down a bolt until it stops and hope that it is tight enough. A single bolt, inaccurately or incorrectly tightened, can lead to the failure of the complete product.”

If a bolt torque is too tight, you risk a stripping or bolt shank failure. If the torque is too low, the bolt tension won’t meet functional requirements. Either outcome can cause significant problems.

The Top 5 Reasons Why Nuts and Bolts Come Loose

Industrial bolts are used in various applications and environments, and feature an advantage that isn’t present in other fastening methods: they can be loosened as needed.

But with this advantage comes a problem: nuts and bolts can come loose without warning. In this blog post, we’ll look at some of the ways that can happen.
