Park Tool introduced the bicycle world to the three-way hex wrench over 40 years ago.
Our Y-shaped wrenches fit perfectly in the palm of your hand and provide excellent leverage, making them a favorite of mechanics in bike shops worldwide.

The ergonomically-shaped tool body features a glass fiber reinforced polymer center. Each wrench is made from heat-treated industrial tool steel for long life, with chamfered tips for a perfect fit. 

The AWS-7 features three of the most common fittings found on modern bicycles, allowing adjustment of brakes, handlebars, stems, and more.
