F436 Zinc-Plated Washers are hardened flat washers designed to provide a smooth, even bearing surface for high-strength bolts and nuts. Manufactured to ASTM F436 specifications, these washers deliver exceptional strength, durability, and load distribution—ideal for structural, industrial, and heavy-duty bolting applications.

The zinc-plated finish enhances corrosion resistance, providing long-lasting protection in both indoor and mildly corrosive environments while maintaining a clean, professional appearance.

Key Features:

• Meets ASTM F436 standards
• Zinc-plated for corrosion protection
• Hardened steel for superior strength and wear resistance
• Ensures even load distribution under bolt heads and nuts
• Ideal for use with B7 studs and 2H nuts
