I like big bolts and I can not lie

We've been having some pretty big stuff come through lately - and I love it!!!!

These are 2 1/2 inches in diameter & 9 inches in length - they're gigantic!

And these beauties are 1" diameters x 7 1/2" - also HUGE!

I made a letter 'J' out of them.

How big is the allen wrench that will turn this?!

I could barely lift one!
