The set includes a 12-inch hardened steel blade and cast iron heads — a square head and a center head — providing versatile reference angles for scribing, checking squareness, and locating center points on round stock. The blade is graduated in the 4R style, offering four graduation scales: 1\/16, 1\/32, 1\/64, and 1\/8 inch. At 3.2 pounds, the set is solid and stable during use. Machinists, pipefitters, fabricators, and skilled tradespeople rely on combination square sets like this for accurate layout work.\u003c\/p\u003e\n\u003cp\u003eThis combination square set is suited for residential and commercial trade applications wherever precise linear and angular measurement is required. Common uses include scribing parallel lines, checking 90-degree and 45-degree angles, finding the center of cylindrical workpieces, and depth measurement. The cast iron heads resist wear and maintain accurate contact with the blade channel over extended use. The set is appropriate for shop environments, job site fabrication, and mechanical rooms where layout tools see regular use.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3-piece set includes 12-inch hardened steel blade, square head, and center head\u003c\/li\u003e\n  \u003cli\u003e4R graduation style: 1\/64, 1\/32, 1\/16, and 1\/8 inch scales on a single blade\u003c\/li\u003e\n  \u003cli\u003eCast iron heads for durability and consistent blade-to-head fit\u003c\/li\u003e\n  \u003cli\u003eHardened steel blade resists flex and wear under repeated use\u003c\/li\u003e\n  \u003cli\u003eCenter head allows quick, accurate centerline location on round or square stock\u003c\/li\u003e\n  \u003cli\u003eCompact package — 1 set per package, minimum order quantity of 1\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 12-inch blade layout tool systems.

Before use, verify the blade is fully seated and the locking nut is tightened securely against the head to prevent blade shift during measurement. Clean the blade channel and mating surfaces periodically to maintain accurate head-to-blade registration. Store in a protective case or designated tool storage to prevent damage to graduated surfaces.\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: 12 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGraduation Style\u003c\/strong\u003e: 4R\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGraduation Scales (Inch)\u003c\/strong\u003e: 1\/64, 1\/32, 1\/16, 1\/8 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Types\u003c\/strong\u003e: Square Head, Center Head\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: 3.2 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 13-265-4\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51695012872498,"sku":"13-265-4","price":108.35,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/583ba039b928d3e62137334297605c1a.jpg?v=1788330506","url":"https:\/\/voomisupply.com\/products\/spi-13-265-4-combination-square-set-12-inch-3-piece","provider":"Voomi Supply","version":"1.0","type":"link"}
