A fastener system includes a fastener or nail for mounting objects on a surface and a corresponding plug for filling a hole left when the nail is removed from the surface. The nail and plug are formed of an engineering plastic, and may be formed from recycled materials. In embodiments, the nail and plug are joined by an arm which is easily broken away. In embodiments, the fastener and plug each have a plurality of flanges which provide strength and grip the surface.

A fastener for fastening pipes or electrical conduit can be installed with the optional use of nails or screws. The fastener includes sharp teeth or spikes which can be hammered into an external surface, such as wood or masonry. The teeth or spikes are positioned, oriented, and otherwise configured to best suit the intended application. Installation can be accomplished using only the fastener itself and force exceeding a minimal threshold.

Implementations of a covered opening fastener are provided. In some implementations, the covered opening fastener comprises a shelf and a shaft or one or more spikes.

In some implementations, a method for using the covered opening fastener comprises attaching the covered opening fastener to an edge portion of a first object, such as a first roofing part, and driving the covered opening fastener into and/or through a second object, such as a second roofing part, to thereby attach the first object and the second object together by the covered opening fastener without forming an opening through the first object.

A polymeric fastener for use in the construction industry for fastening wood and other basic materials together. The polymeric fastener can be formed in the basic shape of a nail and/or a staple-like fastener. Preferred embodiments of the polymeric fastener include a hardened binder embedded with a filler and/or a core for adequate strength as required for use with a delivery device powered by pneumatics, hydraulics, or other mechanical systems.

The present disclosure provides several anchor assemblies for hanging or otherwise securing an object to a wall, particularly those with wallboards including gypsum. The assemblies include a frame and an insert that cooperate to provide a mounting surface. At least one of the frame and insert include one or more prongs for penetrating wallboard. The anchor can be secured to and removed from the wall with relative ease, while causing minimal damage to any punctured wallboard.

A fastener includes a self-locking pin washer and at least one elongate projection mounted on the self-locking pin washer, where the self-locking pin washer is arranged to be a resistance fit to a projection mounted on a structure or vehicle. A method of fastening a panel to a substrate includes attaching a fastener to a projection of a substrate, wherein the fastener includes an elongate projection that is longer than the projection. The method further includes attaching a panel onto the elongate projection of the fastener.

Mounting device for inserting insulation holders into insulation material, where the mounting device comprises a drive head adapted to drive the insulation holder through a central opening of the head portion of the mounting device, where the central opening is provided with a threaded portion, where the lead pitch of the threaded portion is at least 30 millimetres. The advantage of the invention is that insulation holders can be inserted into insulation material in an easy and cost-effective way. An insulation holder can be driven completely through the central opening since the insulation holder does not have a protruding head. The insulation holder is provided with a thread corresponding to the thread of the central opening, such that the insulation holder is screwed into the insulation material.

An impact device includes a drive assembly, a cam having a ramp and a fall-off, and a follower associated with the cam. During rotation of the cam, one of the cam or the follower axially displaces as the follower traverses the cam and falls off the fall-off to transform the rotary motion of the drive assembly to a reciprocating motion having a saw-tooth shape that includes a gradual retraction and a quick extension. The quick extension creates an impact loading, which can be used, for example, for driving a fastener into a work piece.
