Lock Washers

Lock washers are a subcategory of washers that feature a locking mechanism. While there are various styles of lock washers, including split lock washers, toothed lock washers, and more, they are all designed to create secure connections that resist loosening due to vibration or other factors. With steel and stainless steel material options and various finish options, lock washers can be used in an extensive range of industrial applications.
