What Is Fastener?

In woodworking and construction, a nail is a small object made of metal (or wood, called a tree nail or “trunnel”) which is used as a fastener, as a peg to hang something, or sometimes as a decoration.[1] Generally, nails have a sharp point on one end and a flattened head on the other, but headless nails are available. Nails are made in a great variety of forms for specialized purposes. The most common is a wire nail. Other types of nails include pinstacksbradsspikes, 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 laterally. The point of the nail is also sometimes bent over or clinched after driving to prevent pulling out.

Types of nail include:

  • Aluminum nails – Made of aluminum in many shapes and sizes for use with aluminum architectural metals
  • Box nail – like a common nail but with a thinner shank and head
  • Brads are small, thin, tapered, nails with a lip or projection to one side rather than a full head[16] or a small finish nail[17]
    • Floor brad (‘stigs’) – flat, tapered and angular, for use in fixing floor boards
    • Oval brad – Ovals utilize the principles of fracture mechanics to allow nailing without splitting. Highly anisotropic materials like regular wood (as opposed to wood composites) can easily be wedged apart. Use of an oval perpendicular to the wood’s grain cuts the wood fibers rather than wedges them apart, and thus allows fastening without splitting, even close to edges
    • Panel pins
  • Tacks or Tintacks are short, sharp pointed nails often used with carpet, fabric and paper[18] Normally cut from sheet steel (as opposed to wire); the tack is used in upholstery, shoe making and saddle manufacture. The triangular shape of the nail’s cross section gives greater grip and less tearing of materials such as cloth and leather compared to a wire nail.
    • Brass tack – brass tacks are commonly used where corrosion may be an issue, such as furniture where contact with human skin salts will cause corrosion on steel nails
    • Canoe tack – A clinching (or clenching) nail. The nail point is tapered so that it can be turned back on itself using a clinching iron.[19] It then bites back into the wood from the side opposite the nail’s head, forming a rivet-like fastening.[20]
    • Clench-nails used in building clinker boats.[21]
    • Shoe tack – A clinching nail (see above) for clinching leather and sometimes wood, formerly used for handmade shoes.[22]
    • Carpet tack
    • Upholstery tacks – used to attach coverings to furniture
    • Thumbtack (or “push-pin” or “drawing-pin”) are lightweight pins used to secure paper or cardboard.
  • Casing nails – have a head that is smoothly tapered, in comparison to the “stepped” head of a finish nail. When used to install casing around windows or doors, they allow the wood to be pried off later with minimal damage when repairs are needed, and without the need to dent the face of the casing in order to grab and extract the nail. Once the casing has been removed, the nails can be extracted from the inner frame with any of the usual nail pullers
  • Clout nail – a roofing nail
  • Coil nail – nails designed for use in a pneumatic nail gun assembled in coils
  • Common nail – smooth shank, wire nail with a heavy, flat head. The typical nail for framing
  • Convex head (nipple head, springhead) roofing nail – an umbrella shaped head with a rubber gasket for fastening metal roofing, usually with a ring shank
  • Copper nail – nails made of copper for use with copper flashing or slate shingles etc.
  • D-head (clipped head) nail – a common or box nail with part of the head removed for some pneumatic nail guns
  • Double-ended nail – a rare type of nail with points on both ends and the “head” in the middle for joining boards together. See this patent. Similar to a dowel nail but with a head on the shank.
  • Double-headed (duplex, formwork, shutter, scaffold) nail – used for temporary nailing; nails can easily pulled for later disassembly
  • Dowel nail – a double pointed nail without a “head” on the shank, a piece of round steel sharpened on both ends
  • Drywall (plasterboard) nail – short, hardened, ring-shank nail with a very thin head
  • Fiber cement nail – a nail for installing fiber cement siding
  • Finish nail (bullet head nail, lost-head nail) – A wire nail with a small head intended to be minimally visible or driven below the wood surface and the hole filled to be invisible
  • Gang nail – a nail plate
  • Hardboard pin – a small nail for fixing hardboard or thin plywood, often with a square shank
  • Horseshoe nail – nails used to hold horseshoes on hoofs
  • Joist hanger nail – special nails rated for use with joist hangers and similar brackets. Sometimes called “Teco nails” (1+12 × .148 shank nails used in metal connectors such as hurricane ties)
  • Lost-head nail – see finish nail
  • Masonry (concrete) – lengthwise fluted, hardened nail for use in concrete
  • Oval wire nail – nails with an oval shank
  • Panel pin
  • Gutter spike – Large long nail intended to hold wooden gutters and some metal gutters in place at the bottom edge of a roof
  • Ring (annular, improved, jagged) shank nail – nails that have ridges circling the shank to provide extra resistance to pulling out
  • Roofing (clout) nail – generally a short nail with a broad head used with asphalt shingles, felt paper or the like
  • Screw (helical) nail – a nail with a spiral shank – uses including flooring and assembling pallets
  • Shake (shingle) nail – small headed nails to use for nailing shakes and shingles
  • Sprig – a small nail with either a headless, tapered shank or a square shank with a head on one side.[23] Commonly used by glaziers to fix a glass plane into a wooden frame.
  • Square nail – a cut nail
  • T-head nail – shaped like the letter T
  • Veneer pin
  • Wire (French) nail – a general term for a nail with a round shank. These are sometimes called French nails from their country of invention
  • Wire-weld collated nail – nails held together with slender wires for use in nail guns
