The long shaft of the allen key / 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 length is optimally selected to minimize the wind-up and flex experienced with longer wrenches.
The hex wrench / allen key is made from Bondhus ProtaniumTM high torque industrial steel for long life.
Special "speed bearing"attachment facilitates installation and removal of long-threaded socket head bolts and nuts.
The offset P-handle is made from a durable nylon material which is ergonomically-designed for comfortable use.
