I'm in the process of installing a side case rack on my motorcycle, which is from a Spanish company. The installation instructions specify using a drill size of '016' but don't provide any units. What is that equivalent to in North American drill bit sizes? Would it be close to 5/8 inches? The SHAD website isn't providing any help for this conversion, so any insight would be appreciated!

It looks like '016' is actually referring to millimeters, which means it's approximately 5/8 inches. Just so you know, '016' isn't a standard way to label drill sizes in the U.S., which can make things a bit confusing. Good luck with your installation!
In North America, drill sizes are expressed in letters, numbers, and fractions. The '016' could likely be a number size, but it's not directly convertible to common U.S. sizes. I'd recommend checking out some drill size charts online for more options. Just make sure to double-check the fit before you drill!

Thanks for the clarification! I figured it might be millimeters since everything is metric these days.
