Professional Applications & Engineering Value

This bronze split lock washer is engineered to address critical vibration-induced loosening in mechanical assemblies. The bronze material offers inherent corrosion resistance, making it ideal for applications in marine, chemical processing, and outdoor equipment where moisture and corrosive agents are present. The split lock design creates continuous spring tension against both the fastener and bearing surface, effectively maintaining clamp load in high-vibration environments such as motors, pumps, and heavy machinery. Meeting ASME B18.21.1 standards, these washers provide reliable performance in inch-system applications requiring precise No. 6 screw compatibility. The combination of Rockwell B90 hardness and precise dimensions ensures consistent performance while preventing damage to connected components.
