The OEMTOOLS 87165 7 Piece 3/8” Drive Offset Oil Filter Wrench Set is made for oil filters that use a welded hex nut rather than fluted sides on the body of the filter. Not every oil filter is designed the same, or located in the same spot under the hood. When it comes to oil changes, the ability to adapt to new conditions is the name of the game. These offset oil filter sockets make it easy to access hex nut style oil filters tucked away in less accessible spaces under the hood, keeping your oil changes running smoothly from project to project. Their slim low profile design lets them get between various kinds of equipment. You can attach them to your preferred 3/8 inch drive ratchet or wrench of choice without having to purchase a specialty wrench for these sockets. Best of all, they fit neatly in their included storage case that's compact enough to travel with you on the go. For off-kilter projects, reach for the OEMTOOLS Offset Oil Filter Sockets.
