It features a 50-degree primary angle and a 130-degree complementary angle, giving tradespeople two reference surfaces in a single compact tool. The one-piece stainless steel construction resists corrosion and holds its geometry under shop conditions. At 0.01 pounds, it is lightweight enough for frequent handheld use without fatigue. Machinists, tool-and-die workers, and fabricators reach for this type of gage when checking mating angles on workpieces, fixtures, or setups.\u003c\/p\u003e\n\u003cp\u003eThis angle gage is suited for precision layout and inspection tasks on the shop floor or at the bench. It works well for checking bevels, chamfers, dovetails, and other angular features where a fixed-reference gage is faster and more repeatable than a protractor. Both primary and complementary angles are ground into the tool, so the same gage covers inside and outside angle checks without flipping to a second instrument. Typical users include machinists, quality-control technicians, and tool makers working in production or job-shop environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e50-degree primary angle and 130-degree complementary angle in one tool\u003c\/li\u003e\n  \u003cli\u003eStainless steel construction resists corrosion and wear\u003c\/li\u003e\n  \u003cli\u003eFixed-reference design provides consistent, repeatable angle verification\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.01 pounds for easy one-handed use\u003c\/li\u003e\n  \u003cli\u003eCompact form factor suits both bench inspection and in-process checks\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a fixed-reference angle gage for general-purpose angular measurement and inspection in machining and fabrication applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eNo installation is required for this hand tool. Keep the reference surfaces clean and free of burrs before use to ensure accurate contact with the workpiece. Store in a protective case or pouch to prevent nicking the precision ground edges. Periodically verify the gage against a certified angle block if critical tolerances are involved.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Angle\u003c\/strong\u003e: 50 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eComplementary Angle\u003c\/strong\u003e: 130 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 41111619\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: 31-389-0\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51694564835634,"sku":"31-389-0","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3f6f7226a07cb8d4bda8e57b7a1e2d6f.jpg?v=1788325559","url":"https:\/\/voomisupply.com\/products\/spi-31-389-0-stainless-steel-angle-gage-50-130-degree","provider":"Voomi Supply","version":"1.0","type":"link"}
