The Conquest F436 Flat Washer, Plain, is engineered to deliver consistent performance under high-load environments. Built for use in conjunction with structural bolts, these washers distribute pressure evenly while protecting surfaces and preventing damage under tightened assemblies. Whether you're anchoring steel columns, setting heavy machinery, or working on critical infrastructure, these washers provide the durability and performance professionals count on.
Manufactured to meet ASTM F436 specifications, this washer series supports high-strength fastening systems, especially in construction and industrial applications. The plain (uncoated) finish makes them suitable for indoor or controlled environments where corrosion resistance is not a primary concern.
Available in multiple sizes, these washers can be paired with various bolt diameters. Each option ensures a precise fit and reliable performance in high-stress applications.
Features:
ASTM F436 Compliant: Engineered for use with A325 and A490 structural bolts.
Plain Finish: Ideal for applications where corrosion exposure is minimal.
Heavy-Duty Design: Withstands high clamping pressures without deforming.
Precision Machined: Ensures uniform thickness and smooth seating surface.
Multiple Sizes Available: Choose the right fit for your specific bolt and load requirements.
Applications:
Steel-to-steel structural connections
Commercial and industrial construction
Infrastructure and bridge building
Heavy machinery assembly
Equipment base mounting
Installation Notes:
Install between the bolt head (or nut) and the base material to evenly distribute clamping force and minimize surface damage. When used with structural bolts, ensure compatibility in size and material grade to maintain code compliance and safety standards.
