Its stainless steel blade has English graduations of 1/8” and 1/16” as well as metric graduations that are permanently stamped, so you’ll never need to worry about them fading or wearing.  

It features a durable acrylic vial, heavy-duty cast zinc head with a black, chip-resistant e-coating finish, and hardened screw-in scriber that won't fall out so that this combo square can withstand even the roughest job site abuse. 

It was also designed with maximum accuracy in mind - its Auto-Lock™ blade assembly makes it easier to accurately line up your tool for use.
