Professional 15-17mm metric flare nut wrench with Flank Drive® technology, tethering system for height safety, and superior corrosion-resistant construction for aerospace and industrial applications.
The Snap-on Tools@Height 15-17 mm 6-Point Metric Flank Drive Double End Flare Nut Wrench (Model: THRXFMS1517B) is a professional-grade precision tool engineered for demanding industrial applications. This double-ended flare nut wrench features the innovative Flank Drive® wrenching configuration, which grips fastener flats and delivers up to 15-20% more turning power compared to conventional designs. The wrench is manufactured from special alloy steel and heat-treated to optimize strength and durability, ensuring reliable performance in high-stress environments such as aerospace, aviation, military, defense, oil and gas, power generation, and heavy-duty fleet maintenance operations.
The Tools@Height system integrates a secure tethering mechanism with an individual lanyard for each tool, significantly minimizing tool exchanges and reducing the critical risk of drops from heights. The engineered attachment points are strategically designed to not interfere with the tool's functionality, allowing the lanyard to slide out of the way along the wrench handle to provide full operational use and achieve maximum leverage. The polished stainless steel construction provides superior flexibility and exceptional shock-absorbing qualities, eliminating the weakness of welded attachments and delivering a more reliable tool solution.
With a continuous arc design that distributes stress over the entire wrench opening radius, this tool offers enhanced strength and longevity. The tough, durable nickel-chrome plating produces a mirror-like finish that protects against corrosion and facilitates easy cleaning. At 193mm in length and weighing only 0.36 lbs (0.16 kg), this wrench is sized for optimum comfort and balance during extended use, making it an essential addition to any professional tool collection for precision fastening applications.
