Nails are made in a great variety of forms for specialized purposes. The most common is a wire nail. [2] Other types of nails include pins, tacks, brads, spikes, and cleats. Nails are typically driven into the workpiece by a hammer or nail gun. A nail holds materials together by friction in the axial direction and shear strength
Toenailing or skew-nailing is a viable, structurally sound method [1] of the driving of a nail at a roughly 30° [2] angle to fasten two pieces of wood together, typically with their grains perpendicular. The term comes colloquially from fastening wood at the bottom, or toe, of the board.
A nail gun, nailgun or nailer is a form of hammer used to drive nails into wood or other materials. It is usually driven by compressed air , electromagnetism, highly flammable gases such as butane or propane, or, for powder-actuated tools, a small explosive charge. Nail guns have in many ways replaced hammers as tools of choice among builders.
As old growth wood has become much more valuable than the nails that hold it in place, there has been a move toward designs that take out nails with less damage yet.. New designs have been introduced, including the Nail Jack and Nail Hunter nail pullers, which take a pliers-like approach to the old cat's paw design.
Though they vary in design, nailsets are typically made from a hard round or square steel rod which tapers at one end to a flat or slightly hollowed tip. The tip is placed against the head of the nail, while the other end of the nailset is struck with a hammer. [2] Nailsets come with different sized tips suited to different sized nail heads.
They had the advantage of not giving rise to "nail-sickness", a term for decay accelerated and concentrated around metal fasteners. Increased water content causes wood to expand, so that treenails gripped the planks tighter as they absorbed water. [11] However, when the treenail was a different wood species from the planking, it usually caused rot.
The colored straws in the tray contain cartridges that are loaded singly into the tool. Also visible are 75 mm hardened steel nails with 8 mm heads. Powder actuated tools can be variously classified: Direct acting (the charge acts directly on the head of the nail or high velocity), or indirect (using an intermediate piston or low velocity)
