Rug Fastening Device

A rug fastening device for attaching a rug to an installed carpet includes a fastener, which in turn comprises a plate and a screw. The screw is attached to a lower face of the plate and extends helically therefrom. The screw is pointed distal from the plate and thus can penetrate a substrate, such as a rug, a runner, or a mat. The fastener is one of a plurality of fasteners. Each fastener can be screwed through the substrate and into a carpet to affix the substrate thereto to prevent slipping and bunching of the substrate.

Fastener, installation tool and related method of use

A fastener including a chisel point that pre-bores a hole in a work piece to prevent damage to the work piece as the fastener advances. The fastener can include a head, a shaft and a chisel brake point formed at an end of the shaft. The chisel brake point can include first and second opposing inclined surfaces disposed at an angle of about 80° to about 150° relative to one another. A thread can begin adjacent the chisel brake point and form an extension of an inclined surface and/or a chisel edge. The chisel brake point can scrape material from a work piece while pre-boring a hole. The material can be transferred to the thread, and subsequently fed up the thread, out of the pre-bored hole. The chisel brake point can also selectively retard advancement of the fastener into the work piece. Methods of installing the fastener also are provided.

Fastener, installation tool and related method of use

A fastener installation tool including a guide that guides a fastener into a side of a work piece at an angle, while optionally restraining the fastener from wobbling due to rotation, even upon initial entry into the work piece. The guide can define an angled bore including a fastener entrance opening and a fastener exit opening which is adapted to be positioned immediately adjacent the work piece. The guide can include a material ejection port between the openings, through which material bored from the work piece can be evacuated from the angled bore to prevent binding of the material with the fastener. The tool can include a clamp assembly that clamps opposing sides of the work piece to precisely align and steadily hold the angled bore as a fastener is being installed in a side surface. Related methods of using the tool to install fasteners also are provided.
