M5 M8 Carbon steel Galvanized sqaure wahser Grade8.8 Class 8.8 Customized Zinc Plating

Square washers and round washers are essential fasteners designed for gap connection and stress distribution between bolts, nuts, and connecting parts. They effectively reduce friction, limit deformation, transfer pressure, and prevent leakage.

• Shape: Square washers feature equal-length sides with 90-degree angles, while round washers have uniform circumferential edges.
• Applications: Square washers are ideal for square structural connections like angles, I-beams, and rails. Round washers offer broader compatibility for various applications.
• Material Options: Both types are available in steel, copper, aluminum, rubber, and silicone materials, selected based on working conditions.
• Stress Distribution: Round washers provide more uniform stress distribution, while square washers may concentrate force at corners.
• Installation: Round washers allow easier torque control during installation due to their uniform pressure distribution.

• High Strength: Excellent for construction, automotive, and aerospace applications
• Wear Resistance: Ideal for tools, machine parts, and industrial equipment
• Workability: Easily formed through cold working, hot working, and forging processes
• Cost-Effective: Economical solution for large-scale industrial applications

• Requires corrosion protection when exposed to moisture or acidic environments
• Lower shock resistance compared to high-strength alloys

Our galvanizing process applies a protective zinc layer that provides rust resistance and an attractive finish. Available in silver-white standard or passivated colors including white, colored, and army green options.

Our washers are carefully packaged in small packs, cartons, and pallets to ensure safe delivery. Standard package quantity is 100 pieces.
