The Difference Between Screw Shank Nails and Ring Shank Nails

When working in the Industrial Fastening or construction industry, one question that seems to come up often is whether it is better to use Ring shank nails or Screw shank nails. The answer depends on the material being used in the application in order to determine which nails to use.

Screw Shank and spiral nails are often categorized together because both are used for increased withdrawal capacity in hardwoods. However, they are slightly different because Spiral nails also increase driving power in hardwoods. Screw Shank or Spiral nails turn or twist when they are driven – kind of like wood screws, they actually form their own thread in the wood fibers.  These nails are typically used with hardwoods or dense materials. When these nails are used on softwood, they will sometimes split the material resulting in a wasted piece of wood.

 

Ring Shank or Annular NailsImage

Ring shank or annular nails separate the wood fibers, and then the fibers lock back in to the rings which resist removal. These nails are typically used in softer woods. This type of nail is also used for drywall or deck board applications because of the pullout resistant feature of the annular rings on the nail shank. They are designed to provide better grip with material that may otherwise be forced apart by nails. Just like using Screw Shank nails incorrectly on softwood can result in wasted material, using a Ring Shank nail on a piece of hardwood material will cause irreparable damage to the material if the nail is removed.

Summary

Identifying the proper nails to use in different circumstances can result in reduced material costs and minimize the hours of manual labor required.
