Screw nails or screw shank nails are made of carbon steel or stainless steel. They are generally used in hardwoods or dense materials. They form their own thread in the wood fibers, which increase driving power in hardwoods. Usually, these nails are not used on softwood, because they will sometimes split the material.
- Specially designed screw shank for greater holding power in hardwoods.
- Blunt points minimize the damage of the material.
- Commonly with corrosion coating, provides strong rust-proof.
- Easy to remove if necessary.
- Long service life.
