A panel fastener and panel fastening system are provided. The panel fastener includes a body having a collar and an elongated shank extending from the collar. The elongated shank defines an interior space and having a penetrating tip disposed at an end opposite of the collar. The panel fastener also includes a substrate fastening portion configured to be driven into a substrate and a holding mechanism connected to the substrate fastening portion and configured to engage the substrate.

A self-locking fixing device and an antenna assembly are provided. The self-locking fixing device includes an inner mandrel (10) arranged to include a nail head (110) and a nail rod (111) extending away from the nail head (110), and a bushing (114) arranged to include a nail head bushing (124) and a nail rod bushing (125) extending away from the nail head bushing (124). A sidewall of the nail head bushing (124) is provided with at least two elastic clamping units (121). If the inner mandrel (10) is assembled with the bushing (114), the nail head (110) is located in the nail head bushing (124), the nail rod (111) is located in the nail rod bushing (125), and clamping portions of the elastic clamping units (121) are engaged with an upper surface of the nail head (110) to clamp the nail head (110) in the nail head bushing (124). The self-locking fixing device can achieve a good fixing function. When it is applied to an antenna, the PIM and VSWR performance of the antenna can be enhanced, and the rework rate and manufacturing costs may be reduced.

The present invention relates in general to the field of securing structural members to masonry, and more specifically, to a drop-in anchor setting tool and method of use. The drop-in anchor setting tool includes a hands-free safety feature that allows the drop-in anchor and setting tool to remain embedded in the masonry during installation. In particular, the drop-in anchor setting tool includes a threaded portion configured to screw together the drop-in anchor and the drop-in anchor setting tool during installation. A purpose of invention is to provide a drop-in anchor setting tool and method of use that minimizes risk of injury to the operator during installation, is easy to use, and cost-effective to manufacture.

The panel fastener also includes a substrate fastening portion configured to be driven into a substrate and a holding mechanism connected to the substrate fastening portion and configured to engage the substrate.

An anchoring tool includes a driving member defining a striking axis and a driving actuator configured to actuate the driving member along the striking axis to drive a first fastener into a workpiece. The anchoring tool further includes a bending mechanism having a first deforming member configured to deform the first fastener at least partially out of the striking axis.

A fastener includes an elongated body having a striking end, a middle region, and a tip end region. The striking end and the middle region define a longitudinal axis. The striking end has a first cross-section that is substantially equivalent to a second cross-section of the middle region, and the tip end region includes a tip that is offset relative to the longitudinal axis.
