A bracket for attachment to an overhead substrate to carry a suspending wire or rod is formed from metal plate or strap stock having a bend connecting a first generally rectangular section of the stock with a second generally rectangular section of the stock. The first generally rectangular section of stock has a dimple formed on one side of the stock with a corresponding bulge protruding from the other side. The bulge protrudes alongside the second generally rectangular section of stock. The bulge has a base and an apex, a generally conical outside surface adjacent to the first u) generally rectangular section of stock and a through aperture at the apex. The bracket is applied with a tool that can be provided with a washer system to accommodate different fastener lengths and a safety to deactivate the triggering mechanism.

A powered fastener driving tool, and particularly a powder-actuated tool, including in various embodiments both a pipe hook assembly including a pipe hook, and a belt hook assembly including a belt hook.

Various embodiments of the present disclosure provide a fuel cartridge for a gas-powered fastener-driving tool. In one embodiment, the fuel cartridge comprises a body that has a longitudinal axis and that defines an internal fuel storage cavity. The body is shaped and sized to be inserted at least partially into and removed from a housing defined by a case of the tool via translation along the longitudinal axis. The cartridge also includes a connection and fuel dispensing end fitting connected to the body and sized and shaped to engage an end fitting of the tool within the housing. The cartridge also includes a first cam surface extending at least partially around the longitudinal axis and configured to, during relative rotation of the first cam surface and a second cam surface, engage the second cam surface to facilitate removal of the fuel cartridge from the housing.

A powered fastener driving tool such as a powder-actuated tool including a housing assembly including a side wall having a first outer section, a raised section, and a recessed section, the raised section including a rim that extends in an outermost plane of a side wall of the housing and a spring-loaded slidable power setting switch partially positioned in and partially extending from the housing. The spring-loaded slidable power setting switch includes a depressible button movable from a resting position in which an outer surface of the button extends outwardly beyond the plane in which the outer surface of the rim lies to a depressed position in which the outer surface of the button extends in a same or substantially same plane in which the outer surface of the rim lies.

An improved tool for installing an explosively driven fastener as well as an improved explosively driven fastener for use therewith are disclosed. The fastener includes a nail having a head with an explosive load attached thereto in a plastic cap that includes a buffer. The tool has a plurality of concentric cylinders and springs including a muzzle for receiving the fastener head and explosive load. A spring actuated firing pin ignites the load causing it to explode and drive the nail out of the tool. The explosion also automatically resets the tool. The tool and the fastener provide many advantages over existing explosively driven fasteners and the tools used to install them.
