These thoughtfully designed P-handled hex wrenches fit the task at hand, as well as they fit in your hand. All the wrenches fit neatly in the included bench mount/ wall mount holder. The PH-1 set includes 2, 2.5, 3, 4, 5, 6, 8 and 10mm sizes. Long shaft of each wrench is fitted with a Bondhus Balldriver for those hard to reach bolt heads. Short end of the wrench is neatly chamfered and extends from the handle for use when fully tightening bolts in high torque applications. The hex wrenches are made from 8650 chrome vanadium industrial tool steel for long life. Special "speed bearing" attachment facilitates installation and removal of long-threaded socket head bolts and nuts. The offset P-handles are made from a durable nylon material and are ergonomically-designed for comfortable use.
