A handheld electric tightening tool includes a housing and a sealing arrangement. The sealing arrangement is adapted to seal a first portion of the housing from a second portion of the housing and includes a sealing element and a spring. The sealing element includes a first portion adapted to bear against a shoulder formed in the housing, and a second portion adapted to bear against a portion of an outer surface of a rotating axle of the tool. The spring is adapted to at a first end bear against a shoulder formed in the sealing element and at a second end bear against a supporting element arranged on the axle, such that a force is exerted on the sealing element urging the sealing element against the shoulder formed in the housing.

An accessory for use with a rotary power tool having a rotatable spindle and a first mating member. The accessory includes a housing having a body and a plurality of arms extending therefrom, a ball detent selectively engagable with the spindle to lock the accessory to the power tool, a sleeve slidable along the arms between a first position in which the sleeve biases the ball detent into engagement with the spindle to axially secure the accessory to the tool, and a second position in which the ball detent is disengageable from the spindle to release the accessory from the tool, and a second mating member coupled to the arms of the housing.

A powered socket wrench assembly includes a power tool that has a back end and a front end. The power tool is elongated along a longitudinal axis extending between the back end and the front end thereby facilitating the power tool to be inserted into a hard to reach area. Additionally, the power tool includes a chuck that is rotated in a first direction or a second direction when the power tool is turned on. A drive unit is insertable into the chuck on the power tool thereby facilitating the power tool to rotate the drive unit when the power tool is turned on. The drive unit includes a socket that is rotatable about an axis oriented perpendicular to the longitudinal axis of the power tool when the power tool is turned on.
