Small Head Coil Nails: Matching Size, Shank and Finish to the Job

If you build pallets, wooden crates or timber frames, the small head coil nail is probably already on your line. It comes collated in a coil, feeds through a pneumatic coil nail gun, and does the job faster than loose nails. This article walks through the sizing, shank types and finishes available from Linyi Dabao hardware Products co., ltd, and where you can check the full range in person.

What a Small Head Coil Nail Actually Is

A small head coil nail is a wire nail collated into a continuous coil, ready for pneumatic coil nail guns. Instead of loading nails one by one, the operator feeds coil after coil, which is why coil nails dominate high-output pallet plants. Most small head wire coil nails are made from Q235 low carbon steel wire, drawn to a tight diameter so every nail in the coil drives the same. If the wire varies even slightly, you get jams, misfeeds and downtime on the line.

Why the Head Size Matters

The head is smaller than on a standard nail, and that is a deliberate choice. A small head coil nail sits flush with the wood surface, so it does not catch on shrink wrap, scratch cartons or snag workers moving pallets around. For shipping and storage, that clean finish matters as much as holding power. If your customer complains about scratched goods, the head profile is usually the first thing to check.

Matching Nail Length to the Board

The size range for small head coil nails runs from 25 mm to 100 mm, and the right length depends on the material you are joining. A few rules of thumb:

• 25-40 mm for thin boards, plywood panels and light crate work
• 50-70 mm for standard pallet deck boards
• 70-90 mm for pallet stringers and heavier frame members
• 90-100 mm for thick timber and export crates that take real load

Length is not the only dimension that matters. Shank diameter also changes grip, so confirm both when you quote. A factory that stocks the full 25-100 mm range can quote almost any pallet order without waiting for a special run, which is why we keep the full range in stock.

Smooth, Screw or Ring Shank

The shank decides how hard the nail is to pull out. Smooth shank coil nails drive fastest and cost least, and they are fine for general crate work where pull-out is not the main worry. Screw shank wire coil nails have threads that turn into the wood as they drive, sharply increasing withdrawal resistance; they are the choice for heavy pallets and export crates. Ring shank wire coil nails carry rings along the shank that lock into the wood fibers, and they hold tight on reusable pallets that get knocked around for years. Most pallet factories keep two shank types on hand and match the shank to the joint.

Vinyl, Bright or Galvanized

The coating controls feeding and corrosion. Vinyl coated wire coil nails carry a thin vinyl layer that grips the wood after driving and helps the coil slide through the gun, which is why vinyl coated coil nails are standard on high-speed lines. Polished wire coil nails stay bright and bare, a plain finish for indoor work with no moisture. Electro galvanized coil nails add a silver zinc layer for humid workshops, while hot dip galvanized coil nails give a thicker yellow coating for outdoor timber and export packing. We make the same nail in all four finishes, so you can match the coating to the market.

Where Small Head Coil Nails Are Used

Small head coil nails are built for pallet production, wooden crate assembly and timber construction fastening. Pallet plants use them by the ton, crate workshops use them for export packing, and timber builders use them for framing and fencing. Because they arrive collated, a crew can keep driving and only stop to reload, which directly raises daily output on any line.

See the Range at Canton Fair 2026

If you are comparing small head coil nails from different suppliers, the fastest way is to hold them side by side. We will be at the Canton Fair 2026 booth 13.1F39 in the hardware hall from October 15 to October 19, 2026, with samples of every size, shank and finish in our small head coil nails line. You can check the head profile, feel the coating and confirm specs face to face with the factory team, and we can quote on the spot.
