How does a bolted connection work?

The Experts - Basic Bolting

It’s important to know as much as possible about how a bolt functions before being able to solve any bolting challenge.

In this video, Harry Perkins, Design Engineer at Nord-Lock Group, explains the basic characteristics of a bolted joint and how this can affect a bolt’s behaviour.

The Experts - Lubrication and Friction

In this video, Sonny Halberg, Engineer at Nord-Lock Group, explains how friction affects a bolted joint and how lubrication can help!

Did you know that approximately 90% of your torque goes toward overcoming friction and only 10% generates preload in your joint?

The Experts - What is Preload?

In this video Scott Whipkey, Senior Design Engineer at Nord-Lock Group, explains the basics of preload and its function.

Preload is probably the most important part of a bolted joint. Without proper preload, the joint will fail!

The Experts - What is Torque?

In this video, Sandro Vanetta, Sales Engineer at Nord-Lock Group, talks about something very fundamental in the world of engineering: Torque!

The Experts - the Relation Between Torque, Preload and Friction

In this video, Damien Thomas, Technical Manager at Nord-Lock Group, explains how torque, preload and friction interact.

"The break down of torque shows that only 10% of the input torque is useful. All the rest is dissipated by friction. By applying a low friction lubricant, the effect of friction will be greatly reduced," Damien Thomas says.
