The continuous arc jaw design resists spreading under load and delivers greater structural strength compared to older OVO-style geometry. A 45-degree chamfer on each wrench end allows rapid placement on fastener flats even in tight or awkward access points. The satin-chrome finish reduces glare, resists corrosion, and wipes clean quickly during service calls. This wrench meets ANSI B107.6 specifications.\u003c\/p\u003e\u003cp\u003eThe JHW1038A suits residential and commercial service environments where larger fastener sizes are encountered on equipment housings, flanges, piping connections, and structural fittings. It is sold individually and is appropriate for HVAC technicians, plumbers, pipefitters, and general mechanical tradespeople who need a reliable, standard-reach open end wrench in the larger size range. The dual-opening format increases utility by covering two fastener sizes in a single tool.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eDual openings: 1 3\/8 inch and 1 7\/16 inch — two fastener sizes in one wrench\u003c\/li\u003e\n\u003cli\u003eContinuous arc jaw design minimizes spreading and outperforms OVO-style construction\u003c\/li\u003e\n\u003cli\u003e45-degree chamfer on wrench ends allows easy placement on fastener flats in restricted spaces\u003c\/li\u003e\n\u003cli\u003eSatin-chrome finish provides corrosion resistance, reduced glare, and easy cleaning\u003c\/li\u003e\n\u003cli\u003eMeets ANSI B107.6 federal specification for open end wrenches\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard open end wrench for use with 1 3\/8 inch and 1 7\/16 inch fasteners across a wide range of mechanical, HVAC, plumbing, and pipefitting applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eUsed by licensed HVAC technicians, plumbers, and pipefitters in equipment service and installation work. Always de-energize and isolate the system — electrical, gas, or water — before applying hand tools to fasteners on live equipment. Confirm fastener size before applying the wrench to avoid rounding flats. Do not use extension bars or cheater pipes on standard open end wrenches, as this can cause jaw spreading or fastener damage.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOpening Sizes\u003c\/strong\u003e: 1 3\/8 inches and 1 7\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 16.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 2.9 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2.27 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Satin Chrome\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: ANSI B107.6\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: Each\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: WILLIAMS COMFORT PRODUCTS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: JHW1038A\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WILLIAMS COMFORT PRODUCTS","offers":[{"title":"Default Title","offer_id":51346482168114,"sku":"JHW1038A","price":86.56,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310539906.jpg?v=1782081515","url":"https:\/\/voomisupply.com\/products\/williams-comfort-products-jhw1038a-open-end-wrench","provider":"Voomi Supply","version":"1.0","type":"link"}
