The set includes a 6-inch hardened steel blade and two heads: a square head and a center-finding head. Blade graduations follow the 4R system, providing four scales of measurement: 1\/8 inch, 1\/16 inch, 1\/32 inch, and 1\/64 inch. The hardened steel construction on both the blade and heads delivers durability under shop conditions. Machinists, pipefitters, millwrights, and fabricators rely on this type of set for accurate 90-degree and 45-degree reference, as well as center-finding on round stock.\u003c\/p\u003e\n\u003cp\u003eThis combination square set is suited for use in light fabrication shops, maintenance facilities, and mechanical trades where precise layout work is required. The 6-inch blade length makes it practical for close-quarters work on smaller components and assemblies. The center square head is particularly useful when locating the center of cylindrical parts before drilling or machining. The square head serves general-purpose layout and depth measurement tasks on flat stock and structural components.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3-piece set includes a 6-inch hardened steel blade, square head, and center square head\u003c\/li\u003e\n  \u003cli\u003e4R graduation system: 1\/8 inch, 1\/16 inch, 1\/32 inch, and 1\/64 inch scales\u003c\/li\u003e\n  \u003cli\u003eHardened steel blade resists wear and maintains accuracy under repeated use\u003c\/li\u003e\n  \u003cli\u003eHardened steel head construction for durability in shop environments\u003c\/li\u003e\n  \u003cli\u003eCenter square head allows quick and accurate center-finding on round stock\u003c\/li\u003e\n  \u003cli\u003eCompact 6-inch blade length suits close-tolerance and small-component work\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose combination square set compatible with standard layout and inspection tasks across mechanical, fabrication, and maintenance trades.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis is a hand tool requiring no installation. Handle with care to preserve blade graduation accuracy — avoid dropping or storing loose with heavy tooling. Inspect the blade lock and head seating before use to confirm square is registering true.
