4 Pcs 4 by 4 inch Square Plate Washers Galvanized Washers by YIDU69Q

Description

Product Overview

The 4 Pcs 4 by 4 inch Square Plate Washers are engineered to meet the rigorous demands of industrial fastening applications. Constructed from low carbon steel and finished with an electro‑galvanized coating, each washer offers superior corrosion resistance and a flat, stable surface that distributes load evenly across the bolt head. With a precise 1/4 inch thickness and a pre‑punched 3/4 inch hole, these washers fit standard 3/4 inch bolts without the need for additional drilling or modification. The package includes four identical square plates, each measuring exactly 4 inches on each side, providing a consistent footprint for repetitive assembly tasks. The heavy‑duty design ensures that the washers retain their shape and structural integrity even when subjected to high torque, vibration, or fluctuating temperatures, making them an ideal choice for machinery, structural frames, and maintenance repairs.

Usage

These square plate washers excel in a variety of environments where reliable fastening is critical. In manufacturing plants, they are used to secure motor housings, gearboxes, and conveyor components, preventing loosening caused by constant motion. In construction, the washers provide a stable base for steel joists, pipe connections, and scaffold assemblies, ensuring that load‑bearing joints remain secure over time. Maintenance technicians appreciate the ease of installation; the pre‑punched hole aligns perfectly with standard 3/4 inch bolts, reducing installation time and minimizing the risk of misalignment. Because of their galvanized finish, the washers are also suitable for outdoor applications such as agricultural equipment, irrigation systems, and marine hardware where exposure to moisture and salt can accelerate corrosion on untreated steel. Their flat profile allows them to be stacked or layered when additional spacing or load distribution is required, offering flexibility in custom assembly solutions.

FAQ

What material are these washers made from?

The washers are fabricated from low carbon steel that has been electro‑galvanized. This combination offers a balance of strength, flexibility, and excellent corrosion resistance, making them suitable for both indoor and outdoor industrial applications.

Can these washers be used with bolt sizes other than 3/4 inch?

While the pre‑punched hole is sized for a 3/4 inch bolt, the washer can accommodate slightly larger bolts with a snug fit. For significantly larger bolt diameters, a different washer size or a custom‑drilled hole would be recommended to maintain proper load distribution.

How many washers are included in the package?

Each package contains four individual square plate washers, each measuring 4 inches by 4 inches. This quantity is ideal for projects that require multiple fasteners or for keeping spares on hand for future maintenance.

Are these washers suitable for outdoor or marine use?

Yes. The electro‑galvanized coating provides a protective barrier against moisture, salt, and other corrosive elements commonly encountered in outdoor and marine environments. However, for extremely aggressive conditions, additional protective measures such as sealants may be advisable.

What is the warranty or return policy for these washers?

We stand behind the quality of our products with a one‑year limited warranty covering material defects and manufacturing errors. If you receive a damaged or non‑conforming item, please contact our support team within 30 days for a replacement or refund.
