The leaf measures 0.03 inches thick, 0.5 inches wide, and 12 inches in length, providing a consistent cross-section across the full blade length. Constructed from tempered steel, the blade resists wear and holds its calibrated thickness under repeated use. Machinists, diesel technicians, HVAC technicians, and maintenance professionals reach for this type of gage when checking valve clearances, spark plug gaps, bearing fits, and similar tight-tolerance applications.\u003c\/p\u003e\n\u003cp\u003eThis feeler gage leaf is suited for shop and field use in automotive, industrial, and mechanical service environments. The parallel profile means the blade maintains the same thickness from end to end, which is essential when a uniform gap must be confirmed across a surface. At 12 inches, the blade reaches into deeper clearances where shorter leaves fall short. The 0.5-inch width offers a practical contact surface for most standard clearance checks.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eParallel leaf style maintains consistent 0.03-inch thickness along the full 12-inch length\u003c\/li\u003e\n  \u003cli\u003eTempered steel construction for durability and dimensional stability under repeated use\u003c\/li\u003e\n  \u003cli\u003e0.5-inch width provides reliable contact surface for standard clearance measurements\u003c\/li\u003e\n  \u003cli\u003e12-inch blade length reaches deep clearances in engines and mechanical assemblies\u003c\/li\u003e\n  \u003cli\u003eSingle-leaf format allows use as a standalone gage or replacement in a set\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard parallel feeler gage leaf suitable for use in automotive, industrial, and mechanical maintenance applications where a 0.03-inch clearance measurement is required.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eFeeler gage leaves are installed and used by machinists, diesel technicians, and general maintenance technicians without special tools. Clean contact surfaces before use to avoid false readings caused by debris or oil buildup. Do not force the blade into a gap — drag resistance should be light and consistent when the correct clearance is achieved. Store the leaf flat or in a protective sleeve to prevent bending, which would compromise measurement accuracy.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLeaf Style\u003c\/strong\u003e: Parallel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.03 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\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\u003eMaterial\u003c\/strong\u003e: Tempered Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.04 pounds\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: 52868\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51538395365682,"sku":"52868","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2a6387db7d321b05e14787a1cbafe862.jpg?v=1785824396","url":"https:\/\/voomisupply.com\/products\/starrett-52868-parallel-feeler-gage-leaf-tempered-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
