The Park Tool HCW-4 is a double-ended wrench that fits two common fittings found on adjustable cup-and-cone bottom brackets. One end is compatible with the raised 36 mm wrench flats commonly found on fixed cups, and the opposite end features a pin spanner with two pins to fit many adjusting cups with pin holes. Heat-treated and nickel plated for a lifetime of use.
