Professional-grade 3/4–13/16" double-end flare nut wrench with Flank Drive® system offering 15–20% more turning power, nickel-chrome plating, and ASME® B107.100 compliance for precision fastening in demanding applications.
The Snap-on 3/4–13/16" 6-Point SAE Flank Drive® Double End Flare Nut Wrench (Model RXFS2426B) is a professional-grade tool engineered for precision fastening applications in aviation, aerospace, military, defense, oil and gas, power generation, and heavy-duty fleet maintenance. Manufactured from special alloy steel and heat-treated for optimum strength and durability, this wrench delivers exceptional performance in demanding work environments. The innovative Flank Drive® system grips the fastener flats and provides up to 15–20% more turning power compared to conventional wrenches, reducing the risk of fastener damage and rounding.
This double-end flare nut wrench features a continuous arc design that distributes stress over the entire wrench opening radius for greater strength and longevity. The 6-point configuration ensures secure fastening with minimal slippage, making it ideal for precision work on critical applications. The tough, durable nickel-chrome plating produces a mirror-like finish that protects against corrosion and makes the wrench easy to wipe clean. The wrench is sized for optimum comfort and balance, reducing operator fatigue during extended use. Conforming to ASME® B107.100 standards, this tool meets rigorous industry specifications for quality and performance.
With its dual-end design offering 3/4" and 13/16" sizes in a single tool, this wrench maximizes efficiency and minimizes the need to carry multiple tools. The 8-25/32" overall length provides excellent leverage and control for both tight and loose fastening applications. Whether you're working in aviation maintenance, military operations, or general industrial settings, this Flank Drive® wrench is an essential addition to any professional tool collection.
