Forged from steel with a satin finish, it delivers clean torque transfer on hex fasteners without the jaw slip common to lower-grade alloys. The 15-degree head angle offsets the working plane from the handle, giving a technician clearance to reposition and re-engage the wrench in tight spaces. Licensed mechanics, industrial maintenance techs, and HVAC-R installers who regularly work metric fasteners on compressors, condensing units, and piping flanges will find this a reliable everyday hand tool.\u003c\/p\u003e\n\u003cp\u003eThe J32123 suits any professional or trade environment where metric fasteners in the 21 mm and 23 mm range appear regularly. Common applications include mechanical rooms, equipment pads, rooftop units, and vehicle or fleet maintenance where standard metric wrench sets are the baseline. The dual-size format reduces the number of individual tools a tech carries to a job. The 0.61-pound weight keeps fatigue low during extended fastener work. No special setup is required — the wrench is ready to use out of packaging.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eDual-size heads: 21 mm and 23 mm open end on a single tool\u003c\/li\u003e\n  \u003cli\u003e15-degree head angle for clearance in confined fastener locations\u003c\/li\u003e\n  \u003cli\u003eSteel construction for durability under high-torque applications\u003c\/li\u003e\n  \u003cli\u003eSatin finish resists glare and provides a consistent grip surface\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.61 pounds for reduced hand fatigue\u003c\/li\u003e\n  \u003cli\u003eLifetime warranty coverage from the manufacturer\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with 21 mm and 23 mm metric hex fasteners across industrial, mechanical, and HVAC-R service 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. Always use the correct wrench size for the fastener — do not substitute an adjustable wrench where a fixed-jaw tool is specified. Clean the wrench jaws periodically to maintain full contact with fastener flats.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWrench Size\u003c\/strong\u003e: 21 mm x 23 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 Angle\u003c\/strong\u003e: 15 degrees\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: Satin\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.61 pounds\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: J32123\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PROTO","offers":[{"title":"Default Title","offer_id":51542393946418,"sku":"J32123","price":45.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/53dc8a7be96f137e98932d2e14e8aba2.jpg?v=1785899562","url":"https:\/\/voomisupply.com\/products\/proto-j32123-open-end-wrench-21-mm-x-23-mm-double-end","provider":"Voomi Supply","version":"1.0","type":"link"}
