ATS 3882 9/16 Cylinder Base Wrench

$41.75/Each
Part# 12-04977
MFR Model# 3882-9/16

Overview

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 wrench’s 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 you’ll ever have to purchase.

Quality is okay for occasional use but not for a daily mechanic. The 9/16 fit but the 1/2 inch wrench I purchased would not fit onto the nut because it was too thick and did not have enough clearance to the cylinder wall.
