The offset head geometry positions the handle away from the work surface, giving clearance over raised flanges, panel edges, and obstructed bolt heads. Both ends feature a 12-point box configuration machined from steel with a polished finish. The 12-point design allows engagement every 30 degrees, useful when swing arc is limited. This wrench is a hand-tool staple for HVAC technicians, plumbers, electricians, and pipefitters working on equipment panels, flanged connections, and mechanical assemblies.\u003c\/p\u003e\u003cp\u003eThe J1057M fits into general mechanical service across residential and commercial trade work. It is well suited for equipment room installs, rooftop unit service, panel access work, and any application where a standard straight wrench cannot achieve proper angle on a fastener. The double-end configuration provides two working ends on a single tool, reducing the number of wrenches needed on a job. The polished steel finish resists corrosion during storage and daily shop use.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eDouble-end offset box design provides clearance over raised surfaces and recessed fasteners\u003c\/li\u003e\n\u003cli\u003e12-point box ends allow engagement every 30 degrees for use in limited-swing applications\u003c\/li\u003e\n\u003cli\u003eSteel construction for durability under high-torque hand application\u003c\/li\u003e\n\u003cli\u003ePolished finish for corrosion resistance and ease of cleaning\u003c\/li\u003e\n\u003cli\u003eNon-ratcheting design for straightforward, reliable torque transfer\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard double-end offset box end wrench suitable for use across mechanical, HVAC, plumbing, and electrical trade service applications where 12-point fastener engagement is required.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis wrench is installed and used by hand by licensed tradespeople and experienced service technicians. Always ensure equipment is de-energized, de-pressurized, or otherwise made safe before working on fastened assemblies. Select the correct end size for the fastener to avoid rounding. Do not use extension bars or cheater pipes on a standard non-ratcheting box wrench, as this can damage the tool or the fastener.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWrench Type\u003c\/strong\u003e: Offset Box End Wrench\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Configuration\u003c\/strong\u003e: Double End\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\u003eWeight\u003c\/strong\u003e: 0.27 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27110000\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: J1057M\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PROTO","offers":[{"title":"Default Title","offer_id":51540271235378,"sku":"J1057M","price":36.12,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d74dd1544860365bab9f24f7555f85d9.jpg?v=1785850872","url":"https:\/\/voomisupply.com\/products\/proto-j1057m-offset-box-end-wrench-12-point-double-end","provider":"Voomi Supply","version":"1.0","type":"link"}
