The Conquest F436 Flat Washer is built to meet the rigorous standards of structural and heavy construction applications. Designed for use with A325 and A490 structural bolts, these washers are engineered to distribute load and reduce surface pressure without deforming under stress. Each washer is hot dip galvanized, offering increased corrosion resistance in outdoor and high-moisture environments.

Manufactured to the ASTM F436 specification, these hardened steel washers ensure reliable performance in demanding conditions. Whether you're building a bridge, erecting steel columns, or anchoring a deck post, Conquest F436 washers deliver consistent tensioning and long-term stability.

Available in multiple diameters to suit your fastener size, each washer supports a secure fit and proper bolt tensioning — critical in structural joints that bear high loads.

Features:

• ASTM F436 Specification: Engineered for structural steel connections using A325 and A490 bolts.
• Hot Dip Galvanized Finish: Enhanced corrosion resistance, ideal for exterior and industrial applications.
• Load Distribution: Reduces embedding and bolt head damage, especially in oversized or slotted holes.
• Multiple Size Options: Available in a range of inner and outer diameters to match your fastener requirements.
• Hardened Steel Construction: Maintains integrity under extreme loads and torque.

Common Applications:

• Steel-to-steel connections in commercial construction
• Bridge building, towers, and heavy framing
• Outdoor structural assemblies
• Utility and industrial installations

Installation:

• Ensure compatibility with structural bolts per ASTM standards.
• Place washer under the bolt head or nut to spread the load evenly.
• For galvanized fasteners, use anti-seize compound to prevent thread galling during tightening.
