Park Tool AWS-1 Y-Hex WrenchPark's AWS-1 Allen wrench features a unique Y shape for maximum torque and unsurpassed comfort. 4, 5 and 6mm heads prove useful in almost every repair situation.
Park really nailed it with the ergonomics on this thing. It's small enough to be handy and big enough to be highly torque-able. This is a must in every shop.
No fear of stripping bolts with this one. Nice to have 3 common sizes and easy to get torque with this shape. It's a must have tool for me.
For at-home repairs & adjustments, this 4,5 & 6mm Y wrench is my go-to tool. It's comfortable in my hand, and can fit onto almost every screw on my bike. It's a very good value on Price Point, too!
