The set includes four squares with base lengths of 1-31\/32 inches, 2-31\/32 inches, 3-29\/32 inches, and 6-7\/8 inches, paired with corresponding blade lengths of 2-31\/32 inches, 3-31\/32 inches, 5-29\/32 inches, and 12-1\/32 inches. Accuracy is maintained to within 0.0002 inches. All squares are constructed from stainless steel with hardened and lapped working surfaces for consistent, repeatable measurement across a range of part sizes.\u003c\/p\u003e\u003cp\u003eThis square set is suited for machine shops, tool and die operations, and precision metalworking applications where close-tolerance squareness verification is required. The range of four sizes allows a technician to work across small bench-scale components up to larger workpiece setups without switching tool sets. The fitted plastic case keeps the squares organized and protects the lapped surfaces during storage and transport.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e4-piece set covering base lengths from 1-31\/32 inches to 6-7\/8 inches\u003c\/li\u003e\n\u003cli\u003eAccuracy to 0.0002 inches across all four squares\u003c\/li\u003e\n\u003cli\u003eHardened and lapped stainless steel construction for wear resistance and surface precision\u003c\/li\u003e\n\u003cli\u003eBlade lengths from 2-31\/32 inches to 12-1\/32 inches to accommodate a wide range of workpiece sizes\u003c\/li\u003e\n\u003cli\u003eIncludes a fitted plastic case for organized storage and surface protection\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose precision square set for use in machining, fabrication, inspection, and toolroom layout applications requiring close-tolerance squareness measurement.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eSquare sets are hand tools used for layout and inspection rather than installed components. Handle lapped surfaces with care to avoid contact with abrasives or corrosive materials that could affect accuracy. Store in the fitted case when not in use to protect the precision surfaces. Periodic cleaning with a lint-free cloth and light oil is recommended for long-term surface preservation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Pieces\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBase Lengths\u003c\/strong\u003e: 1-31\/32 inches, 2-31\/32 inches, 3-29\/32 inches, 6-7\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBlade Lengths\u003c\/strong\u003e: 2-31\/32 inches, 3-31\/32 inches, 5-29\/32 inches, 12-1\/32 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAccuracy\u003c\/strong\u003e: 0.0002 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSurface Finish\u003c\/strong\u003e: Hardened and Lapped\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 6 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncludes\u003c\/strong\u003e: Fitted Plastic Case\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: STARRETT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 12229\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51541478637874,"sku":"12229","price":1126.2,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/de47b168b486bc90697ea891399985a6.jpg?v=1785877279","url":"https:\/\/voomisupply.com\/products\/starrett-12229-square-set-4-piece-stainless-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
