The leaf measures 0.003 inches thick, 0.5 inches wide, and 12 inches long, providing a consistent contact surface across the full measuring length. Constructed from stainless steel, the leaf resists corrosion and holds its calibrated thickness through repeated use. HVAC technicians, machinists, and equipment service professionals reach for feeler gages when setting valve clearances, checking bearing end-play, verifying spark plug gaps, or confirming tolerances on rotating equipment during preventive maintenance and installation work.\u003c\/p\u003e\n\u003cp\u003eThis gage is suited for use in both residential and commercial service environments wherever a 0.003-inch clearance must be confirmed or set. Parallel-leaf geometry keeps the contact faces consistent from tip to handle, making it reliable for reaching into tight spaces on compressors, burner assemblies, fan motors, and general mechanical equipment. The 12-inch length allows access to recessed components without requiring a shortened blade. It is sold as a single-leaf replacement, making it a practical add-on when a full gage set is already in use and one blade needs to be replaced.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eParallel leaf style maintains uniform thickness across the full 12-inch length\u003c\/li\u003e\n  \u003cli\u003e0.003-inch calibrated thickness for precise clearance measurement and setting\u003c\/li\u003e\n  \u003cli\u003eStainless steel construction resists rust and corrosion in field conditions\u003c\/li\u003e\n  \u003cli\u003e0.5-inch blade width provides a stable contact surface on flat mating faces\u003c\/li\u003e\n  \u003cli\u003eSingle-leaf format serves as a direct replacement for worn or damaged blades in existing gage sets\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement parallel feeler gage leaf for use with standard feeler gage handles and as a standalone precision measuring blade in general mechanical service applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eFeeler gages require no fasteners or tools to put into service, but the mating surfaces being checked must be clean and free of debris to ensure an accurate reading. Power down or de-energize any equipment before inserting the gage blade near moving parts or electrical components. Do not force the blade into a gap narrower than the blade thickness, as bending or kinking will alter the calibrated dimension and render the gage unreliable. Licensed HVAC technicians and qualified mechanics should follow applicable manufacturer service procedures when using feeler gages for valve, bearing, or burner component adjustments.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.003 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLeaf Width\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLeaf Length\u003c\/strong\u003e: 12 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLeaf Style\u003c\/strong\u003e: Parallel\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: 0.1 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: STARRETT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 667S-3\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51543399137586,"sku":"667S-3","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c6b44ec9bad62d21858f94174d5aee10.jpg?v=1785917885","url":"https:\/\/voomisupply.com\/products\/starrett-667s-3-feeler-gage-0-003-in-parallel-leaf-ss","provider":"Voomi Supply","version":"1.0","type":"link"}
