Depth Base for 6" Caliper

The locking nut is a nice touch—it stays put on the blade without slipping. Took a few quick measurements on some drilled holes and got consistent, repeatable depths. Exactly what I needed for this job.

I was surprised how flat and stable this depth base sits against a work surface—it doesn't rock at all during use. The locking nut holds the caliper blade securely without slipping, even when I press firmly. Really glad I picked this up for accurate depth readings on my projects.

The locking nut secures firmly to the blade, so there is no wobble at all during use. It took just a couple seconds to attach and has made measuring step depths in machined parts much more reliable.
