Hengshui, China

We offer Split Washer.Split washers, also known as split lock washers or spring lock washers, feature a single cut that extending from the outside diameter to the center hole. The two ends are misaligned and exert the washer to create a special helical shape - like a donut. And it is this misalignment allows for a positive locking section - creating more friction for better resistance to rotation & loosening.Split washers are extensively used where loosening from vibration and corrosion are primary concerns. Meanwhile, they match well with socket head cap screws and ideal for areas with installation space limitations.Feature: Made from quality spring steel that strongly resists to compression.Allow for greater bolt tensioning for a tighter joint.Thicker than normal flat washers to sustain overall locking effectiveness.Zinc plated for added corrosion resistance and longer lifespan.Prevent loosening by taking up compensates caused by slight friction or vibration.Excellent resistance against both high and low temperature.Durable structure with high hardness.Details: Material: spring steel or stainless steel 304 or 316 upon request.Finish: plain, zinc plating (clear, yellow or black) or oxidation treatment.Style: right handed.Diameter: M2 to M48 or 14" to 3".Standard: GB, ASME, SAE or customize standards.
