    Get a firm hold on flare nuts and fittings to create leak-tight seals on tubing without cracking it. The heads on these wrenches have recessed corners to distribute turning force more evenly than standard wrenches, preventing stripping and slipping. They're well-suited for tight spots on refrigeration, brake, fuel, or hydraulic lines. Also known as flare-nut or line wrenches.
    12-Point Sure-Grip Opening—These wrenches slide onto hex-head fasteners at more angles than those with hex sure-grip openings for quicker engagement. However, they’re more prone to slipping because they make less direct contact with the surfaces.
    Chrome-Plated Steel—The most popular finish, these wrenches won't rust or chip. Although they withstand moisture better than black oxide, they don't hold up to harsh chemicals as well as stainless steel.
    Dull—With a textured finish, these wrenches won't slip out of your hands, even when greasy or oily.
