The set includes a 24-inch hardened steel blade graduated in 16R markings — offering four graduation increments: 1\/100, 1\/32, 1\/50, and 1\/64 inch. A cast iron center square head and a standard square head are included, making this set suitable for a wide range of scribing, squaring, and center-finding tasks. The hardened steel blade resists wear under repeated shop use. Machinists, pipefitters, millwrights, and general tradespeople use this type of set for both bench and field measurement work.\u003c\/p\u003e\n\u003cp\u003eThis combination square set is suited for use on fabrication floors, mechanical rooms, job sites, and machine shops where accurate layout and transfer measurements are required. The 24-inch blade length accommodates larger workpieces that shorter 12-inch sets cannot span. The included center square head is used to locate center points on round stock, while the square head handles 90-degree and 45-degree reference work. This set is appropriate for both residential and commercial trade applications wherever precise linear and angular measurement is needed.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e24-inch hardened steel blade for durability and dimensional stability\u003c\/li\u003e\n  \u003cli\u003e16R graduation style with four increments: 1\/100, 1\/32, 1\/50, and 1\/64 inch\u003c\/li\u003e\n  \u003cli\u003e3-piece set includes center square head and square head\u003c\/li\u003e\n  \u003cli\u003eCast iron heads provide rigidity and resistance to deformation\u003c\/li\u003e\n  \u003cli\u003eCenter head enables fast, accurate center-finding on cylindrical stock\u003c\/li\u003e\n  \u003cli\u003eSquare head supports 90-degree and 45-degree layout and inspection tasks\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 workflows across mechanical, fabrication, and trade applications.

Machinists, pipefitters, and tradespeople should inspect the blade and heads for burrs or damage before use to ensure accurate readings. Store the set in a dry location to prevent corrosion on the hardened steel blade and cast iron heads. Do not overtighten the blade-locking mechanism, as this can damage the graduation markings or distort the head seating surface.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Pieces\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBlade Length\u003c\/strong\u003e: 24 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGraduation Style\u003c\/strong\u003e: 16R\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGraduation Increments\u003c\/strong\u003e: 1\/100, 1\/32, 1\/50, 1\/64 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Types Included\u003c\/strong\u003e: Center, Square\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBlade Material\u003c\/strong\u003e: Hardened Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Material\u003c\/strong\u003e: Cast Iron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 4.8 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: SPI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 13-272-0\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51689192063282,"sku":"13-272-0","price":182.2,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d558dac0941a640e3c12f66fae7fa390.jpg?v=1788255931","url":"https:\/\/voomisupply.com\/products\/spi-13-272-0-combination-square-set-24-inch-3-piece","provider":"Voomi Supply","version":"1.0","type":"link"}
