The set includes a 24-inch hardened steel blade and a hardened steel square head, delivering durability under frequent jobsite use. Graduation markings run in both English and metric scales, with increments as fine as 0.02 inches and 0.5 mm, making this set suitable for precision layout tasks. Machinists, pipefitters, millwrights, and general tradespeople use combination squares for scribing lines, checking squareness, and measuring depth or height with a single tool.\u003c\/p\u003e\n\u003cp\u003eThis combination square set is well suited for residential and commercial construction, mechanical shops, fabrication floors, and maintenance facilities. The 24-inch blade length accommodates larger workpieces and longer layout lines than standard 12-inch sets. The square head allows 90-degree and 45-degree reference checks directly off the blade. Any tradesperson working with steel, wood, or composite materials who needs reliable English and metric measurement on a single blade will find this set fits standard layout workflows.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e24-inch hardened steel blade resists wear and flex during repeated layout use\u003c\/li\u003e\n  \u003cli\u003eHardened steel square head provides stable 90-degree and 45-degree reference surfaces\u003c\/li\u003e\n  \u003cli\u003eDual English and metric graduation for versatile measurement without swapping tools\u003c\/li\u003e\n  \u003cli\u003eFine graduation increments of 0.02 inches and 0.5 mm for precise scribing and layout\u003c\/li\u003e\n  \u003cli\u003e2-piece set covers common combination square tasks in a single package\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose combination square set for trade and industrial layout applications where a 24-inch hardened steel blade with English and metric graduation is required.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eCombination squares require no installation but should be inspected for blade straightness and head locking mechanism function before use. Store the blade protected from impact to maintain graduation accuracy. When using near electrical panels or energized equipment, confirm power is isolated before performing layout work in confined spaces. Periodic cleaning of the blade channel and locking screw ensures consistent head clamping and measurement repeatability.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Pieces\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBlade Length\u003c\/strong\u003e: 24 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBlade Material\u003c\/strong\u003e: Hardened Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Type\u003c\/strong\u003e: Square\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Material\u003c\/strong\u003e: Hardened Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGraduation Style\u003c\/strong\u003e: English and Metric\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGraduation Increments\u003c\/strong\u003e: 0.02 inches, 0.03 inches, 0.5 inches, 1 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 5 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: 13-361-1\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51709149020466,"sku":"13-361-1","price":81.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5bb35281d1fe9468913f7da7122ad536.jpg?v=1788451999","url":"https:\/\/voomisupply.com\/products\/spi-13-361-1-combination-square-set-24-inches-2-piece","provider":"Voomi Supply","version":"1.0","type":"link"}
