1. What are coil nails?

As it’s mentioned in the previous article, Coil Nails are a series of nails arranged in a circle connected by a piece of metal and loaded into a gun.

However, the metal piece isn’t the only type of collation for coil nails. More specifically, coil nails can be classified according to their types of collation, types of screw head, and types of screw shank.

2. Plastic-Collated Coil Nails VS Wire-Collated Coil Nails

Coil nails aren’t necessarily connected by metal wire, they can also be inserted in a plastic strip, which is called Plastic-Collated Coil Nails or Intermediate Coil Nails. For these nails are easily detached from the strip during nailing, the direction of nailing can be unchanged.

Wire-collated coil nails are the most popular type. Compared with plastic-collated coil nails, the price of wire-collated ones is more economic and this type fits the majority of coil nailers. Normally, the nails are connected in a 15 degrees direction with the wire.

Wire-collated Coil Nails are the main products and the most popular type of coil nails in our company. More specifically, these nails can be of smooth shank, screw shank or ring shank.

3. Different Types of Nail Shank

Smooth Shank:

Smooth shank nails have no threading and are the easiest shank type to produce. Naturally, the cost is also relatively lower than other types. With a smooth shank, the nails can be easily driven into any surface and are suitable for a wide range of everyday construction applications. However, the smooth shank nails lack in optimal holding ability and can’t be used in jobs that require great pull-through resistance, such as roofing, etc.

Ring Shank:

Compared with smooth shank nails, with annular threads, ring shank nails have greater holding power. When driven,  ring-shaped threads provide a “locking”  effect with wood material without splitting wood fibers. This kind of coil nails is suitable for softer wood.

Screw Shank:

Screw shank nail is a combination of nails and screws. With a nail’s diamond-shaped point, the nail can be easily driven in; and with a screw’s thread, the nail creates a tight groove that makes the fastener less likely to back out. This kind of thread requires a more complex manufacturing process, which naturally means a more expensive price than the cost of smooth and ring shank nails.

While ring nails are more suitable for softer wood species, screw shank nails are ideal for hardwoods.
