The set includes a hardened steel blade measuring 11-3\/4 inches in length, a cast iron square head, a cast iron center head, and a protractor head. Graduations are marked in both English and metric scales at 1\/32 and 1\/64 inch increments, making this set suitable for precise work across a wide range of measurement tasks. It is a standard layout tool used by electricians, pipefitters, HVAC fabricators, and millwrights who require consistent, repeatable measurements on the job or in the shop.\u003c\/p\u003e\n\u003cp\u003eThis combination square set is used in residential and commercial trade applications where accurate layout and angle measurement are required. The interchangeable head system allows a single blade to serve multiple functions: 90-degree and 45-degree squaring with the square head, center-finding on round stock with the center head, and angle measurement with the protractor head. It is well suited for sheet metal layout, conduit work, pipe fitting, and general fabrication tasks where a reliable, multi-function measuring tool is needed on the bench or in the field.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e4-piece set includes square head, center head, protractor head, and hardened steel blade\u003c\/li\u003e\n  \u003cli\u003eBlade length of 11-3\/4 inches with English and metric graduation markings\u003c\/li\u003e\n  \u003cli\u003eGraduations at 1\/32 and 1\/64 inch increments for fine-resolution layout work\u003c\/li\u003e\n  \u003cli\u003eHardened steel blade resists wear during repeated use in shop and field environments\u003c\/li\u003e\n  \u003cli\u003eCast iron heads provide stable, durable seating against the blade\u003c\/li\u003e\n  \u003cli\u003eInterchangeable head design allows one blade to serve squaring, centering, and angle functions\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 11-3\/4 inch combination square set compatible with general layout and measurement tasks across trade disciplines.
