Hey gearheads and mechanics, listen up! This Speedway Motors AN wrench set is exactly what you need to stop ruining those expensive AN fittings with regular adjustable wrenches. These beautifully CNC manufactured aluminum wrenches are anodized in different colors for quick size identification, plus they've got the actual fitting size stamped right on them - no more guessing games! The set covers all the essential sizes: AN 3 (.511\), AN 4 (.573\), AN 6 (.700\), AN 8 (.886\), AN 10 (1.011\), AN 12 (1.263\), AN 16 (1.513\), and AN 20 (1.850\). What's really smart is how they designed the handles with just the right length to prevent over-tightening - because let's be real, we've all been guilty of cranking down too hard and damaging fittings. The lightening holes not only reduce weight but give you a better grip and that premium 'user friendly' feel. They even throw in a free roll-up case to keep your wrenches organized and protected in your toolbox. Whether you're working on fuel systems, brake lines, or any other AN fitting applications, these wrenches give you that professional fit without chewing up your expensive components. Seriously, if you work with AN fittings regularly, this set will pay for itself by saving just one fitting from getting wrecked by the wrong tool!
