Johnson 12 in. L x 4-3/4 in. H Stainless Steel Combination Square Black

Little tool, big results. Johnson's 12" metal combination square gives you the accuracy and precision you need for every job and was designed to be durable for a lifetime of use. Its stainless steel blade has graduations of 1/8", 1/16" and 1/32" that are permanently stamped so you'll never worry about them fading or wearing. Similarly, the 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 helps this combo square withstand even the roughest job site abuse. It was also designed with maximum accuracy in mind - its square head is CNC machined for greater accuracy, and the Auto-Lock™ blade assembly makes it easier to accurately line up your tool for use.
