Park Tool Y Hex Wrench and Torx Wrench Tool

Park Tool Y-wrenches are designed for bicycle repair, adjustment, and assembly, giving mechanics three common tool sizes in one easy-to-grip handle. The Y-shaped design provides strong leverage and control, making these tools useful for everyday shop work, home bike maintenance, and fast adjustments.

Each variant is made for a specific set of fasteners. The AWS-1 includes 4mm, 5mm, and 6mm hex sizes with chamfered tips for a precise fit. The AWS-8 uses the same 4mm, 5mm, and 6mm sizes but adds ball end tips to reach bolts at an angle. The AWS-3 covers smaller 2mm, 2.5mm, and 3mm hex fittings. The AWS-7 combines 4mm and 5mm hex sizes with a T25 Torx style end, making it useful for modern bikes with both hex and Torx-style hardware.

Choose the model that matches the fastener sizes and access needs for your repair work.
