The Park Tool AWS-7 puts three of the most frequently used fastener sizes on modern bikes into a single Y-shaped tool that fits naturally in your palm. Park Tool introduced the three-way hex wrench to the cycling world over 40 years ago, and the format remains popular in professional shops for good reason: it provides real leverage without the awkward grip angles of L-keys or the fiddly deployment of folding multi-tools.

The AWS-7 combines 4mm and 5mm hex wrenches with a T25 Torx-compatible driver. That trio covers stem faceplate bolts, brake caliper mounting, derailleur cable pinch bolts, handlebar clamps, and disc rotor bolts across most bikes. Having the T25 integrated addresses the growing presence of Torx fasteners in modern component design, particularly on disc brake systems where six-bolt rotors have become standard.

Each wrench arm is made from heat-treated industrial tool steel that has been through-hardened and tempered for durability under repeated use. The chamfered tips engage bolt heads cleanly without the slop that leads to rounded fasteners over time. The central body uses glass fiber reinforced polymer, which keeps weight down while providing a comfortable, slip-resistant grip even with greasy hands or when applying significant torque....
