A fastener setting tool for installing a fastener into a board structure, comprising a tool body having a bottom surface and a longitudinal axis; a spacer assembly, comprising a first abutment member, having a first engagement surface, and a second abutment member, having a second engagement surface opposingly spaced apart from said first engagement surface, each one of said first and second abutment member extending away from and in a direction normal to said bottom surface of said tool body, said spacer assembly being configured to cooperatingly positioningly engage the board structure; at least one fastener guide operably coupled to any one of said first and second abutment member, and configured to guidingly receive a fastener for the board structure; and a spacer adjustment mechanism, adapted to selectively lockingly move at least one of said first and second abutment member in a direction along said longitudinal axis.

A fastener extractor device for removing seized fasteners and aiding in disengaging the extractor device from said seized fastener afterwards. The extractor device includes a shank body, a drive head, a torque-tool body, a tubular sleeve, an external thread, and an internal thread. The torque-tool body includes a plurality of laterally-bracing sidewalls and an at least one engagement feature. The engagement feature is integrated into a specific sidewall to bite into a sized fastener. The drive head is terminally and concentrically connected to the shank body to receive an external torque tool. The torque-tool body is terminally and concentrically connected to the shank body, opposite the drive head. The tubular sleeve is slidably engaged along the shank body through the internal thread and the external thread to physically disengaged the torque-tool body from a seized fastener.

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.

A power screwdriver includes a housing having a vacuum chamber arranged to communicate with a source of sub-atmospheric pressure. The power screwdriver includes a motor, a bit drive spindle, and a bit supporting sleeve connected to the bit drive spindle. The rear end part of the bit supporting sleeve is surrounded by the vacuum chamber. The bit supporting sleeve is journaled by a bearing between a forward end part and a rear end part of the bit supporting sleeve. The bit supporting sleeve includes at least one longitude vacuum passage extending from its rear end part to its forward end part.

An assembly device may include a driver base. The assembly device may also include a driver bit having a main body between a base end and a tip end configured to drive a screw and the main body extending along a longitudinal axis, the driver bit configured to attach to the driver base. The assembly device may also include a vacuum adaptor comprising a forward end, a backward end, and an outer shell enclosing a hollow portion and extending along the longitudinal axis, the backward end configured to attach to the driver base. The assembly device may further include a vacuum nozzle comprising a side wall enclosing a cavity extending along the longitudinal axis from a forward open end to a backward open end opposite to the forward open end. The vacuum nozzle is coaxial with the driver bit and the vacuum adaptor. The backward open end is configured to attach to the forward end of the vacuum adaptor.
