How to Choose the Right Coil Nails?

Coil nails are essential fasteners for pallets, wooden crates and woodworking projects. With various types and specifications, many buyers feel confused when selecting products. Here is a practical guide for you.

First of all, check the nail angle. 21° and 16° are the two mainstream types. 21° coil nails have wide compatibility and fit most ordinary pneumatic nailers, which is the top choice for pallet and crate production. 16° coil nails are special types for matched nail guns, commonly used for imported equipment and precision processing.

Then tell the difference between shank types: smooth shank and ring shank. Smooth shank nails feed smoothly and rarely jam, ideal for temporary fixing. Ring shank nails provide stronger holding power and will not loosen easily, perfect for heavy-load and long-term fastening.

For surface treatment, plain nails are cost-effective for dry indoor environments. Galvanized coil nails feature excellent anti-rust performance, which are recommended for outdoor use, humid warehouses and export packages.

Match the nail size with the wood thickness. Thicker wood and heavier load require nails with larger diameter and longer length. Choosing products from reliable manufacturers ensures stable hardness and avoids broken or bent nails.

Follow the above tips, and you can pick ideal coil nails according to your equipment and working conditions.
