Torquing Our Bolts Correctly

By Mark Taylor 1 years ago 339 Views No comments


Torque: a twisting force that tends to cause rotation. Torque is the amount of energy it takes to spin the nut up along the threads of a bolt. Tension is the stretch or elongation in a bolt that provides the clamping force in a joint.

What happens when you over torque? The process of over torquing is one in which you are tightening a nut or bolt head, and stretching the bolt. You will notice the threads on the bottom bolt appear narrower than the bolt on the top. This bolt has stretched and essentially become weaker. It also makes a worse connection than a properly torqued bolt. While the bolt may feel tight, it is actually a looser connection.

The use of power tools is prohibited in ALL of our installations due to the damage it causes the hardware as well as the boards.

The average power tool is automatically set to torque 800-900ft.lbs.

Our boards are only rated to yield 18ft.lbs, which is 5X less than any power tool is torquing at.

This is an example of what happens when someone uses the wrong tools.

Recommended tool to use:

  • Torque wrench (this tool allows you to set it to the correct torqueing ft. lbs. rated for our products)
