Machined from steel with a polished finish, it features a 12-point box opening on both ends, allowing engagement on hex fasteners from multiple approach angles. The 12-point geometry provides six more contact positions per rotation than a 6-point design, which is useful in tight quarters where swing arc is limited. At 10.7 inches in length and 0.28 pounds, the wrench balances reach with control. It meets ASME B107.10 standards and carries a lifetime warranty from the manufacturer.\u003c\/p\u003e\u003cp\u003eThis wrench is suited for assembly, maintenance, and repair work across mechanical and industrial trades. Electricians, HVAC technicians, plumbers, and general mechanics reach for double-end box wrenches when working on fasteners that require a fully enclosed opening for maximum torque without rounding. The 7\/16 inch and 1\/2 inch size combination covers fastener sizes common in equipment panels, compressor hardware, pipe flanges, and structural connections. The polished steel finish resists corrosion and makes cleanup straightforward in shop and field environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eDouble-end design with 7\/16 inch and 1\/2 inch 12-point box openings\u003c\/li\u003e\n\u003cli\u003e12-point geometry allows engagement from multiple angles in restricted swing situations\u003c\/li\u003e\n\u003cli\u003ePolished steel construction resists corrosion and cleans easily\u003c\/li\u003e\n\u003cli\u003eMeets ASME B107.10 standard for box wrenches\u003c\/li\u003e\n\u003cli\u003eLifetime warranty from PROTO\u003c\/li\u003e\n\u003cli\u003eNon-ratcheting fixed-box design for reliable torque transfer on stubborn fasteners\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard double-end box wrench for 7\/16 inch and 1\/2 inch hex fasteners encountered in mechanical, HVAC, plumbing, electrical, and general industrial service work.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eNo power tools required — this is a hand tool intended for manual fastener work. Confirm fastener size before applying torque to avoid rounding. When working near energized electrical equipment, follow NFPA 70E safe work practices and de-energize circuits before using metal hand tools in close proximity to live conductors. Inspect the wrench for cracks or deformation before each use and do not extend the handle with a cheater bar.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWrench Type\u003c\/strong\u003e: Box End\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Configuration\u003c\/strong\u003e: Double End\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOpening Sizes\u003c\/strong\u003e: 7\/16 inch and 1\/2 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Points\u003c\/strong\u003e: 12\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRatcheting\u003c\/strong\u003e: No\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: Polished\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 10.7 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 0.66 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 0.38 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.28 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: ASME B107.10\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWarranty\u003c\/strong\u003e: Lifetime\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: J111416L\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PROTO","offers":[{"title":"Default Title","offer_id":51540803125554,"sku":"J111416L","price":68.73,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/aac0e91ac2b2735af55aab34f3a50ecd.jpg?v=1785864166","url":"https:\/\/voomisupply.com\/products\/proto-j111416l-box-end-wrench-7-16-x-1-2-in-12-pt-double-end","provider":"Voomi Supply","version":"1.0","type":"link"}
