Each leaf is manufactured from tempered steel and measures 77 millimeters long by 12.7 millimeters wide. The set covers a range from 0.03 mm to 0.5 mm across 13 graduated thicknesses, giving technicians a broad measurement range in a single compact tool. Parallel leaf geometry ensures consistent width from tip to base, making it well suited for applications where uniform blade engagement is required. HVAC technicians, machinists, and general maintenance professionals rely on feeler gage sets like this for checking clearances on valves, bearings, spark plugs, and mechanical linkages.\u003c\/p\u003e\u003cp\u003eThis feeler gage set is appropriate for use in light industrial, commercial, and residential service environments. Common applications include checking compressor valve clearances, motor bearing endplay, burner orifice gaps, and other precision gap measurements encountered during preventive maintenance or equipment installation. The 13-leaf configuration with incremental steps provides enough resolution for most field and shop measurement tasks. Technicians working on HVAC equipment, gas appliances, and mechanical systems will find the range of 0.03 mm to 0.5 mm covers the majority of standard clearance specifications.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e13 tempered steel parallel leaves in a single set\u003c\/li\u003e\n\u003cli\u003eMeasurement range from 0.03 mm to 0.5 mm\u003c\/li\u003e\n\u003cli\u003eLeaf dimensions: 77 mm long by 12.7 mm wide\u003c\/li\u003e\n\u003cli\u003eParallel leaf style provides consistent width along full leaf length\u003c\/li\u003e\n\u003cli\u003eThicknesses included: 0.03, 0.04, 0.05, 0.06, 0.07, 0.08, 0.09, 0.10, 0.15, 0.20, 0.30, 0.40, and 0.50 mm\u003c\/li\u003e\n\u003cli\u003eTempered steel construction for durability in field and shop use\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose parallel feeler gage set suitable for gap and clearance measurement tasks across HVAC, plumbing, electrical, and mechanical service applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eFeeler gages are a measurement tool and do not require installation. Before taking clearance measurements on powered equipment, de-energize the unit and follow applicable lockout\/tagout procedures. Insert leaves gently and avoid forcing blades into tight gaps to prevent bending or damage to the leaf. Clean leaves after use and fan them dry before storing to prevent corrosion on the tempered steel.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Leaves\u003c\/strong\u003e: 13\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Thickness\u003c\/strong\u003e: 0.03 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Thickness\u003c\/strong\u003e: 0.50 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThicknesses Included (mm)\u003c\/strong\u003e: 0.03, 0.04, 0.05, 0.06, 0.07, 0.08, 0.09, 0.10, 0.15, 0.20, 0.30, 0.40, 0.50\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLeaf Style\u003c\/strong\u003e: Parallel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLeaf Length\u003c\/strong\u003e: 77 mm (approximately 3.03 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLeaf Width\u003c\/strong\u003e: 12.7 mm (approximately 0.5 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Tempered Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\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: 57086\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51538876530994,"sku":"57086","price":117.51,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3bc6d07f26721775fffcbb7f29e52f0f.jpg?v=1785828686","url":"https:\/\/voomisupply.com\/products\/starrett-57086-parallel-feeler-gage-set-13-piece","provider":"Voomi Supply","version":"1.0","type":"link"}
