Machined from steel with a polished finish, this wrench features a 12-point box pattern on both ends for positive engagement on hex fasteners. The 12-point design allows repositioning in tighter swing arcs, which is useful in confined spaces. At 7.75 inches in length and 0.19 pounds, it is a lightweight, durable hand tool suited for licensed trades and maintenance technicians who need a reliable wrench for everyday fastener tasks.\u003c\/p\u003e\n\u003cp\u003eThis wrench is appropriate for HVAC installation, plumbing rough-in, electrical panel work, and general mechanical maintenance where 3\/8-inch or 7\/16-inch fasteners are common. It performs well in engine bays, equipment rooms, and tight structural assemblies where a ratchet or open-end wrench may not fit or provide sufficient torque feedback. The double-end configuration reduces the number of tools a technician needs to carry for adjacent fastener sizes.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eDouble-end design covers both 3\/8-inch and 7\/16-inch fastener sizes in one tool\u003c\/li\u003e\n  \u003cli\u003e12-point box profile engages fasteners from multiple positions, useful in restricted swing areas\u003c\/li\u003e\n  \u003cli\u003eSteel construction with polished finish for corrosion resistance and easy cleaning\u003c\/li\u003e\n  \u003cli\u003eNon-ratcheting box end provides maximum torque transfer and durability\u003c\/li\u003e\n  \u003cli\u003eMeets ASME B107.10 standards for hand tool dimensional and performance requirements\u003c\/li\u003e\n  \u003cli\u003eBacked by a lifetime warranty from the manufacturer\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard double-end box wrench for use with 3\/8-inch and 7\/16-inch hex fasteners across residential and commercial trade applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis wrench is a hand tool requiring no installation. Technicians should confirm fastener size before applying torque to avoid rounding fastener heads. Always use the correct end for the fastener being turned. For torque-critical applications, pair with a calibrated torque wrench rather than relying on hand feel alone.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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\u003eDrive Sizes\u003c\/strong\u003e: 3\/8 inch and 7\/16 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Points\u003c\/strong\u003e: 12\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\u003eRatcheting\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 7.75 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: 0.3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.19 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\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: J1012A\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PROTO","offers":[{"title":"Default Title","offer_id":51542324511026,"sku":"J1012A","price":62.33,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8c6f8d2f9728f11ea117056317173c33.jpg?v=1785898177","url":"https:\/\/voomisupply.com\/products\/proto-j1012a-box-end-wrench-3-8-x-7-16-inch-12-point","provider":"Voomi Supply","version":"1.0","type":"link"}
