Johnson Level Tool 406EM 6 in Professional Combination Square

Product Description

The JOHNSON LEVEL TOOL 406EM is a 6-inch professional combination square designed for layout, marking, and checking 90-degree and 45-degree angles on the job site or in the shop. The blade is stainless steel with permanently stamped graduations in both English and metric units, so the markings will not wear off with regular use. The head is heavy-duty cast zinc with a CNC-machined square face for tight dimensional accuracy. A reversible head, lock bolt, and steel screw allow the blade to be repositioned or removed quickly. Carpenters, pipefitters, millwrights, and general tradespeople use this tool for scribing, squaring, and depth measurement tasks.

This combination square is suited for residential and commercial construction, fabrication shops, and maintenance applications where a compact, accurate layout tool is needed. The 6-inch blade length makes it practical for tight spaces and bench work. The dual English and metric graduation system eliminates the need to carry separate tools when working from drawings in either unit system. The hardened screw-in scriber is retained securely in the head and will not fall out during transport or use.
