I like big bolts, and I cannot lie. I have an obsession with big bolts since coming to Diedrich. The first thing I noticed on a Diedrich were the massive bolts on the faceplate of our roasters – they are kind of bronze colored and have six raised little bars on the head. They are all over the machines, even where you can’t see them. In fact, there are over 300 of these bolts, big and little, on an IR-12!

I know, it is a bolt! But that bolt is one of the many invisible details built into our roasters that ensures our quality and strength. Why do we use expensive Number 8 Carbon Steel Bolts throughout our machines? Because it is the right thing to do.

Why do they need to be so robust? Because roasters vibrate and over time that vibration can weaken and fatigue steel bolts. Less strong bolts can eventually fail and break causing enormous damage to the machine. At Diedrich we decided to fix that problem before it ever started.

Those bolts are a metaphor for so many things on a Diedrich Roaster. Why do we care about our automotive quality powder coating? Because it is the right thing to do. Why do we use heavy carbon steel plate for the body of our roasters? Because it is the right thing to do. Why does each new roaster have to pass rigorous testing before it ships? Because it is the right thing to do. Why does every employee in our factory have the power to stop the line if something isn’t made right? Because it is the right thing to do.

So yes, I like big bolts. They are part of what makes a Diedrich special. We spend a lot of time and money focusing on these details because – you guessed it – it is the right thing to do.
