ABSTRACT:
A multiple socket tool combines two, three, or four socket sizes. The sockets are nested inside each other so the tool can be applied to different sizes of bolts or nuts for tightening and loosening such nuts and bolts without changing sockets. Compression springs and pins allow the inner sockets to depress into the larger socket allowing a user automatically to use the proper size. The tool is be driven by a ratchet wrench or an impact gun by connecting to an aperture within the tool. The multi sockets will consist of numerous standard and metric sizes.
