Park Tool Hex 3-Way Wrench 4/5/T25 AWS-7

Refined for Everyday Performance

Over 40 years ago, Park Tool revolutionized bike maintenance with the first-ever three-way hex wrench. Today, the AWS-7 continues that legacy — compact, comfortable, and built to last.

The Y-shaped design fits naturally in your hand, offering superior leverage and control, while the glass fiber–reinforced polymer body ensures durability and comfort during extended use. Each hex is crafted from heat-treated industrial-grade steel with chamfered tips for a precise fit and long-lasting performance.

Featuring three of the most common fittings found on modern bikes, the AWS-7 lets you easily adjust brakes, handlebars, stems, and more — making it an essential in every cyclist’s toolkit.
