It spans two common fastener sizes — 5\/8 inch and 3\/4 inch — in a single forged steel tool with a 15-degree head angle on both ends. The satin finish reduces glare in low-light work environments and resists surface corrosion. This wrench meets ASME B107.6 and federal specification GGG-W-636E, confirming dimensional and strength standards that matter on the job. Designed for licensed tradespeople who need reliable hand tools that hold up under daily use.\u003c\/p\u003e\n\u003cp\u003eThe J3031 fits into standard hand-tool setups used across residential and commercial service work. The 5\/8 inch and 3\/4 inch openings cover fastener sizes common in HVAC equipment mounting, pipe flange connections, electrical panel hardware, and general mechanical assemblies. The 15-degree offset head angle gives clearance when working in tight spaces or around obstructions where a straight-head wrench cannot seat properly. A single-piece steel construction keeps flex minimal and torque transfer consistent across both ends.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eDouble-ended design with 5\/8 inch and 3\/4 inch openings in one tool\u003c\/li\u003e\n  \u003cli\u003e15-degree head angle on both ends for clearance in confined spaces\u003c\/li\u003e\n  \u003cli\u003eForged steel construction for durability under high-torque applications\u003c\/li\u003e\n  \u003cli\u003eSatin finish reduces glare and provides corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eMeets ASME B107.6 and GGG-W-636E standards\u003c\/li\u003e\n  \u003cli\u003eCovered by a lifetime warranty\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard open end wrench for use with 5\/8 inch and 3\/4 inch fasteners across a wide range of mechanical, HVAC, plumbing, and electrical service applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis wrench is used by licensed technicians and tradespeople across multiple trades. Always ensure the wrench jaw is fully seated on a fastener before applying force to prevent rounding. De-energize or shut off the relevant system before working on fasteners near live electrical, pressurized refrigerant lines, or gas connections. Inspect the wrench for cracks or deformation before each use and replace if damage is found.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWrench Size\u003c\/strong\u003e: 5\/8 x 3\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Type\u003c\/strong\u003e: Double end open end\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Angle\u003c\/strong\u003e: 15 degrees\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: 0.39 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ASME B107.6, GGG-W-636E\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWarranty\u003c\/strong\u003e: Lifetime\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: J3031\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PROTO","offers":[{"title":"Default Title","offer_id":51541316370738,"sku":"J3031","price":31.7,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/16b0ba6285b06ca335e6a4a58ff834f4.jpg?v=1785872206","url":"https:\/\/voomisupply.com\/products\/proto-j3031-open-end-wrench-5-8-x-3-4-inch-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
