Constructed from steel with a satin finish, this wrench features a 15-degree head angle that improves clearance and usability in confined work areas. The head width measures 1-49\/64 inches. At 0.36 pounds, it is lightweight without sacrificing durability. Plumbers, pipefitters, HVAC technicians, and electricians keep this type of wrench on hand for fastener work where tool clearance is a constant challenge.\u003c\/p\u003e\n\u003cp\u003eThe J3440 is suited for residential and commercial maintenance, mechanical assembly, and service applications where thin-profile hand tools are required. The 13\/16 x 7\/8 inch jaw sizing covers common fastener dimensions found in plumbing, HVAC equipment, and general mechanical work. Its double-ended configuration allows two fastener sizes to be served by a single tool, reducing the number of tools needed on a job.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eExtra thin profile allows access in restricted and confined spaces\u003c\/li\u003e\n  \u003cli\u003eDouble-ended head provides two jaw sizes: 13\/16 inch and 7\/8 inch\u003c\/li\u003e\n  \u003cli\u003e15-degree head angle improves clearance and swing arc in tight quarters\u003c\/li\u003e\n  \u003cli\u003eSteel construction for durability under trade-use conditions\u003c\/li\u003e\n  \u003cli\u003eSatin finish reduces glare and resists surface corrosion\u003c\/li\u003e\n  \u003cli\u003eLifetime warranty backed by the manufacturer\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style open end wrench for general trade use where 13\/16 inch and 7\/8 inch fastener sizes are required.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis wrench is a hand tool used by licensed tradespeople across HVAC, plumbing, electrical, and mechanical service work. No power source is required, but standard safe-work practices apply: ensure the work area is de-energized or de-pressurized before loosening fasteners on live systems. Select the correct jaw size before applying torque to avoid rounding fastener heads. Inspect the tool before each use and do not use a wrench that shows cracks or deformation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWrench Type\u003c\/strong\u003e: Extra Thin Open End Wrench\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWrench Size\u003c\/strong\u003e: 13\/16 x 7\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Angle\u003c\/strong\u003e: 15 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Width\u003c\/strong\u003e: 1-49\/64 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Satin\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.36 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWarranty\u003c\/strong\u003e: Lifetime\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27110000\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: PROTO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: J3440\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PROTO","offers":[{"title":"Default Title","offer_id":51541371289906,"sku":"J3440","price":37.97,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/cf7175e8d1796f879f646163b955b5e7.jpg?v=1785873869","url":"https:\/\/voomisupply.com\/products\/proto-j3440-extra-thin-open-end-wrench-13-16-x-7-8-in","provider":"Voomi Supply","version":"1.0","type":"link"}
