Metric K-Lock Nuts

Metric K-Lock Nuts are a reusable assembly that replaces hex nuts and lock washers. A free-spinning conical spring or external tooth lock washer is permanently attached to the hex nut; "locking" occurs when the washer contacts and is tightened against the mating surface. Select from zinc plated steel and stainless steel. They are the same as Keps Nuts and are not prone to thread galling.
