16mm Gi Flat Washer

It’s made from hot‑dipped steel for durability, with a zinc/plated finish to resist rust. The surface is smooth and hardened through heat treatment to provide a long‑lasting, high‑strength performance.

Key specs include a 16 mm diameter, heavy‑duty construction, extra thick finish, and a hardened, heat‑treated surface. It is sold per kilogram and is designed for reliable performance in industrial applications.

The hot‑dipped zinc coating creates a protective layer over the steel, significantly improving rust and corrosion resistance, especially in outdoor or humid environments.

It’s ideal for construction, machinery, automotive, and plumbing scenarios where load distribution and corrosion resistance are important. Use it under bolt heads or nuts to protect surfaces and improve joint integrity.

Place the washer between the bolt head (or nut) and the surface, ensuring the 16 mm bolt fits properly. Tighten to achieve a secure, even clamp, making sure the washer sits flat to distribute the load.

Yes, it is sized for 16 mm bolt systems. Confirm the inner/bolt fit and the overall thickness to ensure a proper, secure fit with your hardware.

The washer is sold by weight (per kilogram). The exact number per kg depends on the washer’s thickness and mass per piece, so counts will vary with the specific lot.

Compared with plain steel washers, this GI flat washer offers superior corrosion resistance due to the hot‑dip galvanization and a hardened surface, resulting in longer service life in harsh or outdoor environments.

Choose the 16 mm variant when your bolt system and load distribution require a 16 mm size. If you’re using smaller or larger bolts, consider 12 mm or 20 mm options to match the bolt diameter and load requirements.

Yes. If you’re looking for different sizes, you might consider the 12 mm GI Flat Washer and the 20 mm GI Flat Washer, or the 16 mm Zinc Plated Flat Washer for non‑hot‑dip options.
