f436 washer fastenal

The F436 washer from Fastenal represents a crucial structural hardware component designed for heavy duty bolted connections. This hardened steel washer, conforming to ASTM F436 specifications, features precise dimensional tolerances and superior load distribution capabilities. The washer is engineered with specific hardness requirements, typically ranging between 26-45 HRC, ensuring optimal performance in high-strength structural applications. Its through-hardened construction provides consistent mechanical properties throughout the entire cross-section, making it particularly suitable for use with high-strength structural bolts and heavy hex structural bolts. The F436 washer maintains a flat bearing surface that helps distribute load evenly across the joint, preventing localized stress concentrations and potential material damage. Available in both plain and weathering steel finishes, these washers can be used in various environmental conditions and are especially crucial in steel construction, bridge building, and industrial equipment assembly.

Superior Load Distribution Technology

Superior Load Distribution Technology

The F436 washer's advanced load distribution technology represents a significant advancement in structural fastening systems. The washer's carefully engineered surface profile ensures optimal contact area with both the bolt head and the underlying material, resulting in even pressure distribution across the joint. This feature is particularly crucial in preventing localized stress concentrations that could lead to material fatigue or failure. The washer's precise thickness and flatness tolerances contribute to consistent performance across various applications, while its hardened construction maintains these characteristics even under extreme loading conditions.
Enhanced Durability and Corrosion Resistance

Enhanced Durability and Corrosion Resistance

Durability is a cornerstone feature of the F436 washer, achieved through sophisticated heat treatment processes that ensure consistent hardness throughout the component. The through-hardening process creates a uniform microstructure that resists deformation and wear, significantly extending the washer's service life. When supplied with appropriate finishes, these washers demonstrate exceptional corrosion resistance, making them suitable for exposed structural applications. The combination of material properties and surface treatments provides long-term protection against environmental factors while maintaining structural integrity.
Versatile Application Compatibility

Versatile Application Compatibility

The F436 washer's versatile design makes it compatible with a wide range of structural applications and fastening systems. The standardized dimensions and tolerances ensure proper fit with various bolt grades and sizes, while the washer's load-bearing capabilities make it suitable for both static and dynamic loading conditions. This versatility extends to different industry applications, from heavy construction and infrastructure projects to industrial equipment assembly. The washer's ability to maintain joint integrity under various loading conditions and environmental factors makes it a reliable choice for diverse engineering requirements.
