At 0.004 inches thick and 0.5 inches wide with a 25-foot length, this roll provides ample material for cutting custom feeler gauges or shims on the job. Stainless steel construction resists corrosion and maintains dimensional accuracy across a wide temperature range. HVAC technicians, machinists, and mechanics rely on feeler stock rolls when standard blade gauges lack the length or shape needed for a specific clearance check or fit-up task.\u003c\/p\u003e\n\u003cp\u003eThis feeler stock roll is suited for residential and light commercial applications where technicians need to verify valve clearances, set motor or blower shaft end-play, check bearing fits, or confirm burner orifice spacing. The 25-foot continuous roll allows the installer to cut strips to any required length, making it practical for repetitive production tasks or service calls requiring multiple custom gauges. It is commonly used by HVAC service technicians, pipefitters, and industrial mechanics on equipment where gap tolerances must be held to a few thousandths of an inch.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.004 inch thickness for fine clearance measurement and shimming\u003c\/li\u003e\n  \u003cli\u003e0.5 inch width accommodates a range of gauge and shim cutting applications\u003c\/li\u003e\n  \u003cli\u003e25-foot roll length reduces waste and allows custom-cut strips\u003c\/li\u003e\n  \u003cli\u003eStainless steel material resists rust, oil, and shop-environment corrosion\u003c\/li\u003e\n  \u003cli\u003eConsistent thickness throughout the roll ensures repeatable measurement accuracy\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose feeler stock roll suitable for use wherever a 0.004 inch stainless steel gauge strip is required, including HVAC equipment, mechanical assemblies, and precision machining applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eCut strips from the roll using aviation snips or sharp metal shears to the required length before use. Edges after cutting may be sharp — deburr as needed to avoid injury and to prevent false clearance readings caused by edge burrs. No special tools or trade codes are required for use, but feeler stock handling in live mechanical assemblies should only be performed with equipment fully de-energized and depressurized per standard lockout\/tagout procedures.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.0040 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 25 feet (7.60 meters)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.2 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: 666S-4\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51538348900658,"sku":"666S-4","price":88.75,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1caa2cd104966a3beceb1e3f511b45b1.jpg?v=1785823616","url":"https:\/\/voomisupply.com\/products\/starrett-666s-4-feeler-stock-roll-0-004-in-stainless-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
