The set includes a 12-inch hardened steel blade with 4R graduation markings in 1\/16, 1\/32, 1\/64, and 1\/8 inch increments. Three interchangeable heads — square, protractor, and center — mount to the blade to support a wide range of layout operations. The square head is used for 90-degree and 45-degree reference checks, the protractor head allows angle measurement, and the center head locates the center of round stock. The entire set weighs 2.44 pounds and is suited for machinists, pipefitters, fabricators, and general tradespeople who need reliable layout tools on the job.\u003c\/p\u003e\u003cp\u003eThis combination square set is appropriate for use in fabrication shops, mechanical rooms, plumbing rough-in, and general construction layout. The 12-inch blade length covers a practical range of measuring and scribing tasks on flat stock, pipe, and structural members. The 4R graduation style provides four scales on a single blade, reducing the need to switch tools during layout work. This set is packaged as a single unit and is suitable for both bench use and field service kits.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e4-piece set includes square head, protractor head, center head, and 12-inch blade\u003c\/li\u003e\n\u003cli\u003eHardened steel blade resists wear and maintains graduation accuracy over time\u003c\/li\u003e\n\u003cli\u003eCast iron heads provide stable, repeatable seating on the blade\u003c\/li\u003e\n\u003cli\u003e4R graduation style offers 1\/16, 1\/32, 1\/64, and 1\/8 inch scales on a single blade\u003c\/li\u003e\n\u003cli\u003eInterchangeable head design allows one blade to serve multiple layout functions\u003c\/li\u003e\n\u003cli\u003eCompact weight of 2.44 pounds makes it practical for portable tool kits\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard 4-piece combination square set suitable for general layout and inspection applications across fabrication, plumbing, HVAC, and mechanical trades.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eNo installation is required for hand tools of this type.
