The stainless steel blade carries permanently stamped graduations that resist wear over long-term use. The head is cast zinc with a black, chip-resistant e-coat finish and is CNC machined for accurate 90-degree and 45-degree reference. A reversible head design with a lock bolt and steel screw lets the blade be repositioned quickly without losing setup. A hardened, screw-in scriber is included and secured so it stays in place during transport and use. A durable acrylic level vial is integrated into the head for basic plumb and level checks.\u003c\/p\u003e\n\u003cp\u003eThis combination square is suited for layout, measurement, and marking tasks across carpentry, millwork, plumbing rough-in, electrical panel and conduit layout, and general construction trades. The 12-inch blade length covers standard stud, joist, and panel layout increments. The English graduation system makes it compatible with standard imperial measurement workflows on residential and light commercial jobsites.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eStainless steel blade with permanently stamped graduations for long-term legibility\u003c\/li\u003e\n  \u003cli\u003eCNC machined cast zinc head for repeatable 90-degree and 45-degree accuracy\u003c\/li\u003e\n  \u003cli\u003eBlack chip-resistant e-coat finish on the head resists jobsite wear\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 secured in head to prevent loss\u003c\/li\u003e\n  \u003cli\u003eIntegrated acrylic level vial for quick plumb and level reference\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 12-inch combination square for general layout and measurement use across multiple trades and applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eNo installation is required for this hand tool.
