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.\u003c\/p\u003e\n\u003cp\u003eThis 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.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eStainless steel blade with permanently stamped English and metric graduations for lasting legibility\u003c\/li\u003e\n  \u003cli\u003eCNC-machined cast zinc square head for improved accuracy at 90 and 45 degrees\u003c\/li\u003e\n  \u003cli\u003eBlack chip-resistant e-coating finish on the head for corrosion and impact protection\u003c\/li\u003e\n  \u003cli\u003eReversible head with lock bolt and steel screw for flexible blade positioning\u003c\/li\u003e\n  \u003cli\u003eHardened screw-in scriber retained securely in the head\u003c\/li\u003e\n  \u003cli\u003eDurable acrylic level vial integrated into the head\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standalone professional layout tool compatible with standard combination square accessories and replacement blades sized for 6-inch combination square heads.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eNo power source or wiring is required for this tool.
