Countersunk External-Tooth Lock Washer
Manufacturer part: 90069A215
These washers grip flat- and oval-head countersunk screws, so you get a secure hold without overtightening. They resist loosening in applications with constant motion, such as conveyors. Tooth lock washers typically can't be reused because the teeth often get bent when tightened. External Tooth—Teeth on the outside edge bite into both the screw head and the mating surface to lock the assembly in place. Black-Oxide Steel—Typically chosen for their appearance, these washers have a dark, matte coating that creates a finished look. They offer minimal corrosion resistance, so they're best for dry environments.
