Constructed from steel with a chrome-plated finish, this wrench resists corrosion and cleans up easily on the job. The double-end head configuration gives two working ends in a single tool. Both ends are ground to 15-degree and 60-degree head angles, allowing access to fasteners in restricted spaces where a straight pull is not possible. It meets GGG-W-636E standards and carries a lifetime warranty, making it a long-term addition to any trade toolkit.\u003c\/p\u003e\n\u003cp\u003eThis wrench is suited for use across HVAC, plumbing, electrical, and general mechanical service applications wherever 9 mm fasteners appear. The compact size and dual-angle head design make it practical for residential and light commercial service work, including equipment panels, pipe fittings, and mechanical assemblies. The chrome finish holds up to shop and field conditions. Technicians working on unit connections, bracket hardware, or component mounting will find the offset angles useful when clearance is limited.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eDouble-end open end head with 15-degree and 60-degree offset angles for restricted-space access\u003c\/li\u003e\n  \u003cli\u003e9 mm jaw size fits metric fasteners used in HVAC, plumbing, and mechanical equipment\u003c\/li\u003e\n  \u003cli\u003eChrome-plated steel construction for corrosion resistance and durability\u003c\/li\u003e\n  \u003cli\u003eHead width of 3\/4 inch for a low-profile grip on fastener flats\u003c\/li\u003e\n  \u003cli\u003eMeets GGG-W-636E wrench standards\u003c\/li\u003e\n  \u003cli\u003eBacked by a lifetime warranty\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose metric open end wrench compatible with 9 mm 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 a hand tool used by licensed HVAC technicians, plumbers, electricians, and mechanical service professionals. Always ensure the jaw is fully seated on the fastener flats before applying torque to prevent rounding. When working on energized systems or pressurized lines, de-energize or depressurize the system before using hand tools on fittings or hardware. Keep the chrome surface clean and dry to maintain finish integrity and prevent slipping.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWrench Size\u003c\/strong\u003e: 9 mm\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 Angles\u003c\/strong\u003e: 15 degrees and 60 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Width\u003c\/strong\u003e: 3\/4 inch\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: Chrome-Plated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.06 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: GGG-W-636E\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: J3109M\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PROTO","offers":[{"title":"Default Title","offer_id":51542237806898,"sku":"J3109M","price":36.8,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/72da7e6d199d3d9d1f6c158f1bba674d.jpg?v=1785896016","url":"https:\/\/voomisupply.com\/products\/proto-j3109m-9mm-double-end-open-end-wrench","provider":"Voomi Supply","version":"1.0","type":"link"}
