OVERVIEW Stop using kit-included allen keys or hardware store tools and equip yourself with our Titanium-Nitride wrenches. Our wrenches feature tips made from HSS (High Speed Steel) blanks. The blanks are precision ground to size, then true to their namesake, are coated in Titanium Nitride (TN-coated) for strength and durability. The 18mm O.D. handles are made from anodized aluminum, hollowed for less weight, and are also color-coded and laser etched with the measurement labels for easy and quick identification.
