The ATS 3882-series Cylinder Base Nut Wrenches are made from forged alloy steel, tempered, and hardened for maximum strength. They also have an industrial chrome plating to improve surface wear, and protect against rust and corrosion. Their thin-wall construction guarantees they will fit nuts close to the cylinder casing without grinding down the wrenchs outer diameter. And with a 15" span, they clear even the tallest cylinders. In fact, the 3882 Cylinder Base Wrenches address just about every concern of the previous 2882 series, while including several enhancements to make your work easier. They also carry the ATS Pro lifetime warranty, so they may very well be the last cylinder wrenches youll ever have to purchase.

TIP: Most Continental engines will require either a 1/2" or a 9/16" wrench. The notable exceptions are the IO-520 and the O-470 engines which require a 5/8" (and sometimes a 9/16") wrench. The Lycoming Wide Decks also use these wrenches (most commonly the 3/4" wrench). Additionally, a few of the older Continental engines will require the 3/4" wrench.
