Fastener setting tool

A fastener setting tool for installing a fastener into a board structure, the fastener setting tool comprising:

• a tool body having a flat bottom surface extending from at least a first abutment member to a second abutment member and a longitudinal axis;
• a handle connected to the tool body and extending above an upper surface of the tool body, wherein the flat bottom surface of the tool body is opposite the handle,
• a spacer assembly including:
• the first abutment member having a first engagement surface, and
• the second abutment member having a second engagement surface opposingly spaced apart from the first engagement surface,
• wherein the first and second abutment members each extends away from and in a direction normal to the bottom surface of the tool body,
• wherein the first and second abutment members are engageable with the board structure, and
• wherein the first abutment member has a first vertical spacing portion extending towards a first distal end and towards a first proximal end in a direction parallel to the bottom surface,
• wherein the second abutment member has a second vertical spacing portion extending towards a second distal end and proximal towards a second proximal end in a direction parallel to the bottom surface,
• wherein the first and second vertical spacing portions are configured to prevent the board structure from directly contacting the bottom surface;
• a fastener guide operably coupled to one of the first and second abutment members, and configured to guidingly receive a fastener for the board structure;
• and
• a spacer adjustment mechanism, at least one of the first and second abutment members selectively lockingly movable by the spacer adjustment mechanism in a direction along the longitudinal axis, wherein the spacer adjustment mechanism includes a guideway formed in the tool body along the longitudinal axis and extending a width of the tool body and at least halfway of the length of the tool body, the guideway including a lower guide surface and an upper guide surface, each guide surface including a plurality of locking teeth arranged complementary opposite to one another and operably spaced along the guideway, and a slider assembly disposed within the guideway, engageable with the teeth and resiliently biased towards an engaged position.
