Park Tool 錐形扳手 28mm (SCW-28)

Took the rear axle nut off my touring bike with zero slipping—the Y-head grips flats so much better than my old adjustable wrench. It’s thin enough to get into tight caliper spots, and the steel feels solid in hand. Two weeks of shop use and it hasn’t rounded a single edge.

The "Y" head design really grips better than a standard wrench, no rounding of the flats. Used it on a tandem wheel build and it held fast. Only wish it came with a bit more length for leverage on stubborn nuts.

The Y-shaped head on this 28mm wrench lets you get a solid grip on thin hub locknuts without slipping. Only tiny knock is the price feels a bit steep for a single wrench, but the precision is undeniable for wheel work.
