Q: What sizes are included?
A: The set includes five fractional flare nut wrenches (¼x5/16, ?x7/16, ½x9/16, ?x11/16, ¾x? inch) and six metric sizes (9x11, 10x12, 13x14, 15x17, 16x18, 19x21 mm).
Q: Why use a flare nut wrench instead of a regular wrench?
A: Flare nut wrenches grip tubing fittings (such as those on brake and fuel lines) with better contact and less risk of slipping or rounding the nut, especially on soft metals like brass or aluminum.
Q: What does the SureGrip design offer?
A: SureGrip box ends engage the sides of the fastener rather than the corners, which improves torque application and reduces damage to worn or corroded fittings.
