Checking Your Bolt Torque

06/06/2017 08:30 AM

Knowing how to check bolt torque is a key ingredient in making sure fasteners don’t fail. There are several ways to determine bolt torque, including torque auditing.   As Bill Eccles of Bolt Science writes, there are three ways this can be achieved: “Each of these three methods have their deficiencies,” Eccles says. “The key […]

How to Avoid Bolt Failure

05/23/2017 07:30 AM

“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 […]
