Leaf thicknesses range from 0.0010 to 0.0350 decimal inch, giving technicians a wide measurement spread in a single compact set. Each leaf is 3-1\/32 inches long and 1\/2 inch wide, with a parallel profile that keeps contact surfaces consistent across the full leaf length. HVAC technicians, machinists, plumbers, and industrial maintenance professionals use feeler gages to check valve clearances, bearing fits, spark plug gaps, and flange alignment tolerances.\u003c\/p\u003e\u003cp\u003eThis set suits residential and light commercial maintenance tasks where precise clearance verification is required. The stainless steel construction resists corrosion and wear, making it appropriate for use in humid mechanical rooms, boiler rooms, and field service environments. The 31-leaf configuration covers the most commonly needed decimal-inch thicknesses, reducing the need to carry multiple sets on a service call.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e31 stainless steel leaves covering 0.0010 to 0.0350 decimal inch\u003c\/li\u003e\n\u003cli\u003eParallel leaf style for consistent contact across the full leaf surface\u003c\/li\u003e\n\u003cli\u003eLeaf length of 3-1\/32 inches with 1\/2 inch width for access in tight clearances\u003c\/li\u003e\n\u003cli\u003eStainless steel material resists rust and corrosion in wet or humid environments\u003c\/li\u003e\n\u003cli\u003eCompact set weight of 0.3 pounds for easy carry in a tool bag or pouch\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose decimal-inch feeler gage set suitable for mechanical clearance measurement tasks across HVAC, plumbing, and industrial maintenance applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eFeeler gages are a measurement tool, not an installed component. Select the appropriate leaf thickness for the gap being measured and insert it with light, consistent hand pressure. Do not force leaves into tight clearances, as this can deform the leaf and compromise accuracy. Keep leaves clean and lightly oiled when stored to prevent corrosion and maintain calibration integrity.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Leaves\u003c\/strong\u003e: 31\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Thickness\u003c\/strong\u003e: 0.0010 decimal inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Thickness\u003c\/strong\u003e: 0.0350 decimal inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThicknesses Included (decimal inch)\u003c\/strong\u003e: 0.0010, 0.0015, 0.0020, 0.0025, 0.0030, 0.0260, 0.0280, 0.0300, 0.0320, 0.0350\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: 3-1\/32 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLeaf Width\u003c\/strong\u003e: 1\/2 inch\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: 0.3 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 3.6 inches (L) x 0.8 inches (W) x 0.8 inches (H)\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: 66BS\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51538686607666,"sku":"66BS","price":153.6,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/dd6f7111e8e8b96fd1623f44041f5960.jpg?v=1785825623","url":"https:\/\/voomisupply.com\/products\/starrett-66bs-feeler-gage-set-31-leaves-stainless-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
