Screw Checker, Large Metric, PEC

I've been using this screw checker daily in my workshop and the metric sizing is spot-on for all my fasteners. The chrome-plated carbon steel really does hold up well against the occasional drop on concrete.

The chrome-plated finish feels rock solid, and the large metric markings are crisp enough to read at a glance even in dim workshop light. I've used it to sort out a mixed bin of bolts and it's already saved me from guessing wrong on a few stubborn sizes.

Finally got around to comparing my random bin of metric screws, and this checker sorted them all in a few minutes. The carbon steel body has a nice solid heft that makes it feel like it'll outlast my toolbox.
