• a driving mechanism disposed within the housing for driving the fastener into a workpiece;
• a trigger attached to the housing for activating the driving mechanism;
• a nosepiece cover pivotally attached to the nosepiece;
• a latch pivotally attached to the nosepiece cover;
• and
• a spring pivotally attached to the latch for engaging at least one hook disposed on the nosepiece,
• wherein the spring has first and second legs extending along a longitudinal axis of the nosepiece and a cross-bar connecting the legs and extending across the nosepiece, each of the first and second legs having at least two bends.

A fastener tool comprising:

• a housing comprising a nosepiece;
• a magazine connected to the housing for storing a fastener;
• a driving mechanism disposed within the housing for driving the fastener into a workpiece;
• a trigger assembly pivotally attached to the housing for activating the driving mechanism;
• and
• a nosepiece cover pivotally attached to the nosepiece;
• wherein one of the nosepiece and the nosepiece cover have a protrusion contacting the other of the nosepiece and the nosepiece cover upon rotation of the nosepiece cover for limiting rotational motion range of the nosepiece cover relative to the nosepiece.

A fastener tool comprising:

• a housing comprising a nosepiece;
• a magazine connected to the nosepiece for storing a fastener, the magazine having top, side and bottom walls, a fastener loading space disposed between the top and bottom walls, a door movable between the top and bottom walls, and a pusher disposed in the fastener loading space for pushing the fastener towards the nosepiece;
• a driving mechanism disposed within the housing for driving the fastener into a workpiece;
• a trigger assembly pivotally attached to the housing for activating the driving mechanism;
• wherein the top wall of the magazine has a window disposed near the nosepiece for showing when a low number of fasteners remains in the magazine.

A fastener tool comprising:

• a housing comprising a nosepiece and a handle;
• a magazine assembly connected to the housing for storing a fastener, the magazine assembly comprising an upper magazine with a rail for receiving a fastener head, a lower magazine fixedly attached to the upper magazine, the lower magazine defining a fastener channel and a pusher channel, and a pusher assembly for pushing the fastener towards the nosepiece, the pusher comprising a carriage which slides along the rail, a pin extending from the carriage extending into the pusher channel, an upper pusher pivotally attached to the pin, the upper pusher having a tab which can be moved by a user, a lower pusher pivotally attached to the pin, the lower pusher having a contact surface for contacting the fastener and pushing the fastener towards the nosepiece, and a spring for biasing the upper and lower pushers towards the fastener channel;
• a driving mechanism disposed within the housing for driving the fastener into a workpiece;
• and a trigger assembly pivotally attached to the housing for activating the driving mechanism;
• wherein the lower pusher has a camming surface to bypass fasteners inserted into the magazine assembly when the pusher assembly is moved towards the end of the magazine assembly farthest from the nosepiece, and the upper magazine having at least one indentation near the end of the magazine assembly farthest from the nosepiece for latching the upper pusher.

A method for using a fastener tool with a magazine assembly, comprising the steps of:

• providing a pusher assembly in the magazine assembly that can bypass fasteners inserted into the magazine assembly and that can be releasably locked at the rear end of the magazine assembly;
• in a first mode of operation, inserting fasteners into the magazine assembly, and moving the pusher assembly towards the rear end of the magazine assembly;
• and
• in a second mode of operation, moving the pusher assembly towards the rear end of the magazine assembly, locking the pusher assembly at the rear end of the magazine assembly, inserting fasteners into the magazine assembly, and releasing the pusher assembly.

A fastener tool comprising:

• a housing comprising a nosepiece and a handle;
• a magazine assembly connected to the housing for storing a fastener, the magazine assembly comprising a magazine defining a fastener channel and a pusher channel, and a pusher assembly for pushing the fastener towards the nosepiece, the pusher assembly sliding along the pusher channel and comprising a pusher for contacting the fastener and pushing the fastener towards the nosepiece, and a spring for biasing the pusher towards the fastener channel;
• a driving mechanism disposed within the housing for driving the fastener into a workpiece;
• and a trigger assembly pivotally attached to the housing for activating the driving mechanism;
• wherein the pusher has a camming surface to bypass fasteners inserted into the magazine assembly when the pusher assembly is moved towards the end of the magazine assembly farthest from the nosepiece, and the magazine having at least one indentation near the end of the magazine assembly farthest from the nosepiece for latching the pusher.

A power tool comprising:

• a working portion configured to be applied to a workpiece;
• a housing coupled to the working portion, the housing including a driving mechanism for driving the working portion to perform an operation to a workpiece;
• and a handle extending from the housing, the handle having first and second portions;
• a switch coupled to at least one of the housing and the handle for activating the driving mechanism;
• and
• a hook assembly having a annular member rotationally disposed between the first and second portions of the handle, and a hook portion extending from the annular member,
• wherein the annular member has a first positive stopping element that engages a second positive stopping element on one of the first and second portions of the handle.

A handle for a power tool that includes a working portion configured to be applied to a workpiece, a housing coupled to the working portion and including a driving mechanism for driving the working portion to perform an operation to a workpiece, and a switch coupled to at least one of the housing and the handle for activating the driving mechanism, the handle comprising:

• a grip portion extending from the housing;
• an end cap configured to be coupled to the grip portion;
