What kind of hardware do you use and how do I maintain it?

UPDATED SEPTEMBER 2023

The rack itself is mainly anodized aluminum with stainless steel fasteners (screws, bolts and nuts) and some brass bushings. There are also a few Delrin parts. Delrin is an engineering thermoplastic used in precision parts requiring high stiffness, low friction, and excellent dimensional stability.

The fasteners are torqued at the factory and because of the chemical properties of steel mated to aluminum, need no thread-lock solution.

Any mechanical connection can vibrate and loosen, so it is a good idea to occasionally check the fasteners and other parts to make sure they are secure and tight. This is normal wear and tear.
