The Xcelite 99PS40BP 11-Piece Ballpoint Allen Hex Socket Screwdriver Set features compact interchangeable blades designed for recessed socket head screws. The blades each have a unique ballpoint tip that makes the kit ideal for tightening and removing Allen type socket head screws in out-of-reach places or merely when wanting an easier, quicker way to drive them home. The blades will engage a screw head from any angle, with the tip slipping easily into sockets and holding securely without reaming.

The set also includes the Model 99X5 extension, which adds 4 inches in length. The model 991 Handle holds the blade shaft firmly, yet permits quick, easy insertion and removal. The blades are made from high-quality steel, hardened and tempered for optimum performance. The set is supplied with a convenient see-through stand-up plastic case.
