Stanley 69-257-22 Allen Key Set(Pack of 12)

Allen keys are used for tightening and removing screws, nuts and bolts that have hexagonal driving slots. With 12 differently sized Allen keys, this key set is designed to help you perform a variety of tightening and loosening jobs. These extra-long imperial keys help you tighten screws that are located in hard-to-reach areas. While using the shorter arm you can extract more torque to fasten screws with ease. The longer arms of these tools have ball tips for tightening or loosening the fasteners at awkward angles.
