Professional 10-12mm metric flare nut wrench with integrated safety tether system, Flank Drive technology for superior grip, and polished stainless steel construction for demanding elevated work environments.
The Tools@Height 10-12mm 6-Point Metric Flank Drive Double End Flare Nut Wrench (Model THRXFMS1012B) is a professional-grade tool engineered for aviation, aerospace, and industrial maintenance applications. This innovative wrench features Snap-on's proprietary tethering system that securely attaches each tool with its own integrated lanyard, significantly minimizing tool exchanges and reducing the critical risk of drops in elevated work environments. The wrench is manufactured from special alloy steel and heat-treated to deliver optimum strength and durability, ensuring reliable performance in demanding professional settings.
The 6-Point box end incorporates the proven Flank Drive wrenching configuration, which grips fastener flats and provides up to 15-20% more turning power compared to conventional designs. The continuous arc design distributes stress evenly over the entire wrench opening radius, resulting in greater overall strength and extended tool life. Constructed from polished stainless steel, this wrench offers superior flexibility and shock-absorbing qualities that surpass welded attachments, with no welds to fail. The engineered attachment points are strategically positioned to not interfere with tool functionality, while the lanyard slides smoothly along the wrench handle to provide full use and maximum leverage.
With tough, durable nickel-chrome plating that produces a mirror-like finish, this wrench provides excellent corrosion protection and remains easy to clean and maintain. Weighing just 0.15 lbs (0.07 kg) with a total length of 153mm, the wrench is sized for optimum comfort and balance during extended use. The 10-12mm double end design accommodates multiple fastener sizes, making it an essential tool for professionals working at heights where safety and reliability are paramount concerns.
