## Description

Product Description Little tool, big results. Johnson's easy to use 6" combination square gives you the accuracy and precision you need for every job. Its stainless steel blade has english graduations of 1/8", 1/16" and 1/32" as well as metric graduations that are permanently stamped, so you'll never 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 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. From the Manufacturer A necessary tool for any tradesman, this combination square is handy for any number of different project and tool-setup applications from woodworking, to stonemasonry to metalworking. Because the highly accurate CNC-machined head acts as a stop, it guarantees your layout lines are always square to the edges, making it ideal as a machinist's square, a straightedge, an adjustable try square, a miter square, a marking gauge and a depth gauge.

Review: Great small combo square - I recently purchased the Johnson Level & Tool 406EM Professional Inch/Metric Combination Square, and I must say, it has far exceeded my expectations in terms of quality, value, and usability. I have a number of larger squares but needed something smaller for a project. Given its surprisingly affordable price, I was initially skeptical about its performance and durability. However, after using it extensively in various projects, I'm thoroughly impressed. It's a tool that not only meets but exceeds expectations, and I wholeheartedly recommend it to anyone in the market for a reliable combination square.
Review: compact for tool pouch/bag - I like the smaller size of this unit and i can use it in smaller places. the quality is impressive. i still keep it wrapped for protection when in my tool bag.
