Chase Bays – CB-ANWRENCHSET – Billet Aluminum AN Wrench Set – 12 pc

If you’ve ever used AN wrenches you know one specified size does not fit all. In the AN fitting world, there is “B Nut” and “S Nut” sizing. A -6AN wrench can fit a -6AN Hose End perfectly, but another brand or another run of -6AN fittings won’t work that same wrench. That would be a B Nut vs. S Nut scenario. Chase Bays’ wrench set includes ALL in between sizing so this is the last purchase you will make. Instead of trying to call them with an S or B suffix, Chase Bays calls them 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, and 12. Some of these sizes don’t exist in the AN fitting world (IE: 2, 7, 9, 11) but it made the most sense for the in-between sizes.

Chase Bays have used their 12 years of AN fitting experience to manufacture the most precise and most inclusive set available. This is the same set they use every day to assemblehundreds of AN fittings with no scratches or marks. Don’t waste your time with other kits that will only fit half of your fittings, and definitely don’t get the “adjustable” AN wrenches. They do not work well.

These wrenches are 3/8″ inch | 9.6mm thick aerospace 6061 billet aluminum with a UV proof black hard anodized finish.
