This innovative wrench features Snap-on's proprietary Tools@Height tethering system, which securely attaches each tool with its own lanyard to minimize exchanges and significantly reduce the risk of costly drops in elevated work environments.\n \n Manufactured from special alloy steel and heat-treated for optimum strength and durability, this wrench delivers exceptional performance and reliability. The 6-point box end features the proven Flank Drive wrenching configuration that grips fastener flats and provides up to 15-20% more turning power compared to traditional designs. The polished stainless steel construction offers superior flexibility and shock-absorbing qualities, while the continuous arc design distributes stress over the entire wrench opening radius for maximum strength and longevity.\n \n The wrench measures 223mm in length with a 32-34mm outside diameter and 12-13mm head depth, weighing only 0.555 lbs (0.25 kg) for optimal comfort and balance. The engineered attachment points are strategically positioned to not interfere with tool functionality, and the lanyard slides out of the way along the handle to provide full use and achieve greatest leverage. Protected by tough, durable nickel-chrome plating that produces a mirror-like finish, this wrench resists corrosion and wipes clean effortlessly, making it an essential tool for professional technicians and maintenance crews.\n  \u003c\/div\u003e\n  \n  \u003c!-- Features section (always included) --\u003e\n  \n  \u003cdiv class=\"features-section\"\u003e\n  \u003ch2 class=\"section-title\"\u003eKey Features\u003c\/h2\u003e\n  \u003cul class=\"features-list\"\u003e\n  \u003cli class=\"feature-item\"\u003eSnap-on Tools@Height tethering system with individual lanyard minimizes tool exchanges and prevents costly drops\u003c\/li\u003e\u003cli class=\"feature-item\"\u003e6-Point Flank Drive configuration provides up to 15-20% more turning power than traditional designs\u003c\/li\u003e\u003cli class=\"feature-item\"\u003eDouble-end design with 19-21mm metric sizing for versatile fastener applications\u003c\/li\u003e\u003cli class=\"feature-item\"\u003ePolished stainless steel construction with superior flexibility and shock-absorbing qualities\u003c\/li\u003e\u003cli class=\"feature-item\"\u003eContinuous arc design distributes stress over entire wrench opening radius for maximum strength\u003c\/li\u003e\u003cli class=\"feature-item\"\u003eNickel-chrome plating provides corrosion resistance and mirror-like finish for easy cleaning\u003c\/li\u003e\u003cli class=\"feature-item\"\u003eEngineered attachment points do not interfere with tool functionality or handle leverage\u003c\/li\u003e\u003cli class=\"feature-item\"\u003eSpecial alloy steel construction heat-treated for optimum strength and durability\u003c\/li\u003e\u003cli class=\"feature-item\"\u003eOptimally sized at 223mm length for comfort and balance during extended use\u003c\/li\u003e\u003cli class=\"feature-item\"\u003eNo welds to fail - superior design ensures long-term reliability\u003c\/li\u003e\n  \u003c\/ul\u003e\n  \u003c\/div\u003e\n  \n  \u003c!-- Specifications section (always included) --\u003e\n  \n  \u003cdiv class=\"specs-section\"\u003e\n  \u003ch2 class=\"section-title\"\u003eTechnical Specifications\u003c\/h2\u003e\n  \u003ctable class=\"specs-table\"\u003e\n  \u003cthead\u003e\n  \u003ctr\u003e\n  \u003cth\u003eSpecification\u003c\/th\u003e\n  \u003cth\u003eValue\u003c\/th\u003e\n  \u003c\/tr\u003e\n  \u003c\/thead\u003e\n  \u003ctbody\u003e\n  \u003ctr\u003e\u003ctd\u003eProduct Model\u003c\/td\u003e\u003ctd\u003eTHRXFMS1921B\u003c\/td\u003e\u003c\/tr\u003e\u003ctr\u003e\u003ctd\u003eSize Range\u003c\/td\u003e\u003ctd\u003e19-21 mm Metric\u003c\/td\u003e\u003c\/tr\u003e\u003ctr\u003e\u003ctd\u003eWrench Type\u003c\/td\u003e\u003ctd\u003eDouble End Flare Nut Wrench\u003c\/td\u003e\u003c\/tr\u003e\u003ctr\u003e\u003ctd\u003ePoint Configuration\u003c\/td\u003e\u003ctd\u003e6-Point\u003c\/td\u003e\u003c\/tr\u003e\u003ctr\u003e\u003ctd\u003eDrive System\u003c\/td\u003e\u003ctd\u003eFlank Drive\u003c\/td\u003e\u003c\/tr\u003e\u003ctr\u003e\u003ctd\u003eTotal Length\u003c\/td\u003e\u003ctd\u003e223 mm\u003c\/td\u003e\u003c\/tr\u003e\u003ctr\u003e\u003ctd\u003eOutside Diameter\u003c\/td\u003e\u003ctd\u003e32-34 mm\u003c\/td\u003e\u003c\/tr\u003e\u003ctr\u003e\u003ctd\u003eHead Depth\u003c\/td\u003e\u003ctd\u003e12-13 mm\u003c\/td\u003e\u003c\/tr\u003e\u003ctr\u003e\u003ctd\u003eWeight\u003c\/td\u003e\u003ctd\u003e0.555 lbs (0.25 kg)\u003c\/td\u003e\u003c\/tr\u003e\u003ctr\u003e\u003ctd\u003eMaterial\u003c\/td\u003e\u003ctd\u003eSpecial Alloy Steel\u003c\/td\u003e\u003c\/tr\u003e\u003ctr\u003e\u003ctd\u003eFinish\u003c\/td\u003e\u003ctd\u003eNickel-Chrome Plated\u003c\/td\u003e\u003c\/tr\u003e\u003ctr\u003e\u003ctd\u003eTreatment\u003c\/td\u003e\u003ctd\u003eHeat-Treated for Optimum Strength\u003c\/td\u003e\u003c\/tr\u003e\u003ctr\u003e\u003ctd\u003eTethering System\u003c\/td\u003e\u003ctd\u003eSnap-on Tools@Height with Individual Lanyard\u003c\/td\u003e\u003c\/tr\u003e\u003ctr\u003e\u003ctd\u003eDesign Feature\u003c\/td\u003e\u003ctd\u003eContinuous Arc Design with No Welds\u003c\/td\u003e\u003c\/tr\u003e\u003ctr\u003e\u003ctd\u003ePerformance Advantage\u003c\/td\u003e\u003ctd\u003e15-20% More Turning Power vs. Traditional Designs\u003c\/td\u003e\u003c\/tr\u003e\u003ctr\u003e\u003ctd\u003eList Price\u003c\/td\u003e\u003ctd\u003e$101.00\u003c\/td\u003e\u003c\/tr\u003e\u003ctr\u003e\u003ctd\u003eStock Status\u003c\/td\u003e\u003ctd\u003eBackorder - Estimated 05\/09\/2026\u003c\/td\u003e\u003c\/tr\u003e\n  \u003c\/tbody\u003e\n  \u003c\/table\u003e\n  \u003c\/div\u003e\n  \u003c\/div\u003e","brand":"Snap-On","offers":[{"title":"Default Title","offer_id":45067664130248,"sku":"THRXFMS1921B","price":172000.0,"currency_code":"IQD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0665\/9761\/7864\/files\/de73652b-9163-42ea-a105-296a474bffb0.webp?v=1777327172","url":"https:\/\/toolmart.me\/en\/products\/tools-at-height-19-21mm-flank-drive-flare-nut-wrench","provider":"TOOLMART","version":"1.0","type":"link"}
