These Park Tool thoughtfully designed P-handled hex wrenches fit the task at hand, as well as they fit in your hand. The long shaft of each wrench is fitted with a Bondhus Balldriver for those hard to reach bolt heads. The short end of the wrench is neatly chamfered and extends from the handle for use when fully tightening bolts in high torque applications. Shaft lengths are optimally selected to minimize the wind-up and flex experienced with longer wrenches. The hex wrenches are made from high torque industrial steel and through hardened for long life. The offset P-handles are made from a durable nylon material and are ergonomically-designed for comfortable use.
