An injection molding apparatus including:

a valve pin driven by an actuator, the valve pin extending axially through at least a portion of the channel length of the fluid flow channel, the fluid flow channel including a throat, downstream flow of the injection fluid being restricted by a bulb portion of the pin, the valve pin having an intermediate position where downstream flow of injection fluid is unrestricted and a fully downstream position where downstream flow of injection fluid is stopped at both the gate and at the throat, wherein the actuator is driven by a valve assembly comprised of a spool mechanically driven by first and second actuators or solenoids that each separately engage the spool at opposing axial ends to effect movement of the spool back and forth between the drive fluid flow positions.

The present screw anchor advantageously has two fins radially extending from the body of the screw anchor, where the fins additionally extend above the top end of the body. This unique fin design permits the user to drive the screw anchor into the worn screw hole within a wood substrate so that the screw anchor is substantially flush or recessed within the worn screw hole. When the fins are aligned with the grain of the wood, the fins split the wood at the grain and prevent rotation of the screw anchor. Because the screw anchor is flush or recessed, the anchor does not interfere with the installation of hardware overtop the anchor, such as a hinge. Furthermore, the original screw, such as in the case of a door hinge, can be reused to create an invisible repair.

An anchor fastener includes a head, a generally cylindrical shaft extending from the head, and a base at a distal end of the shaft. The shaft includes a helical thread on an outer surface and a self-drilling tip at its distal end adjacent the base. The base is frangibly connected to the distal end of the shaft by at least one web of frangible material separable from at least one of the base and the shaft under application of a force to the shaft.

A pull-out pin is adapted to couple first and second objects to each other. The pull-out pin is adapted to be removably and tightly inserted through a pin hole of the first object and into a pin hole of the second object. The pull-out pin includes spaced-apart first and second end surfaces, and an outer surrounding surface connected between the first and the second surfaces and surrounding a central axis. The outer surrounding surface has a recessed surface portion defining a vent groove extending from the first end surface in a direction toward the second end surface, and a helical groove extending helically about the central axis from the first end surface toward the second end surface, and intersecting the vent groove.

A setting device for a self-drilling anchor bolt of the present invention includes: a drive shaft, one end thereof having a shank for connecting to an impact tool, and another end being a setting part for pushing the self-drilling anchor bolt axially; a coupling, partially surrounding the drive shaft along an axis, and being supported on the drive shaft in such a way as to be incapable of relative rotation while being axially moveable at least locally; and a releasable locking component, disposed between the drive shaft and the coupling; in a locked position, the locking component is coupled to an extremity of an anchor rod such that the anchor rod is fed axially with rotational striking into a receiving material, and in a released position, the drive shaft strikes a sleeve to advance axially along the anchor rod and expand at an expansion part.

A self-drilling expandable anchor operable with a self-drilling expandable anchor installation tool.

A decking system including a plank and a plug that is configured for insertion into fastener holes of the plank to conceal the fastener holes. The plug may be formed as part of a plug apparatus which may be an injection molded monolithic structure including a support member and a plurality of the plugs coupled thereto. The support member may be a support strip that extends along a strip axis. The plurality of plugs may be connected to the support strip. Each of the plugs may be configured to be detached from the support strip and inserted into a fastener hole in a plank. The plugs may include a first set of the plugs located on a first lateral side of the support strip and a second set of the plugs located on a second lateral side of the support strip opposite the first lateral side.

A panel fastener for removably flush mounting a wall panel to a wood furring. The panel fastener includes a mounting body adapted for being inserted into a complementary opening in the wood furring. A hanger slot is disposed in the mounting body for receiving a hanger member carrying the wall panel. A slot flange is disposed within a portion of the hanger slot and defining a narrowed hanger channel receiving and securing the hanger member. A crush ridge is disposed on a rear side of the slot flange for engaging the hanger member. A slot cap disposed in a rear side of the hanger slot and including a locking arm engaging the hanger member when inserted into the narrowed hanger channel of the slot flange for resisting removal of the hanger member from the narrowed hanger channel.
