f436 lock washer
The F436 lock washer is a crucial mechanical component designed to prevent loosening in bolted joints under dynamic loads and vibrations. This precisely engineered fastener features a unique split ring design with square ends and chamfered edges, manufactured to meet ASTM F436 specifications. The washer is typically made from hardened steel, offering exceptional durability and resistance to deformation. When compressed between the bolt head or nut and the bearing surface, the lock washer's ends create tension against both surfaces, effectively maintaining clamp load and preventing rotation. The F436 lock washer's distinctive design incorporates specific hardness requirements and dimensional tolerances that ensure consistent performance across various applications. These washers are particularly valuable in structural steel construction, heavy machinery assembly, and industrial equipment where maintaining joint integrity is paramount. The washer's surface hardness typically ranges between 38-45 HRC, providing optimal resistance to wear and deformation while maintaining its locking capabilities throughout extended service life. Available in various sizes to accommodate different bolt diameters, the F436 lock washer has become an industry standard for critical fastening applications where reliability and safety are essential considerations.
