This nylon-insert lock nut features a built-in non-metallic locking element that helps prevent the nut from working loose under vibration or mechanical stress. Manufactured to DIN 985 and ISO 10511 standards, it comes with metric threading. The nut is made from stainless steel (A2) with an electrolytic zinc-plated finish, making it well-suited for indoor use or applications with minimal exposure to the elements. The zinc coating on stainless steel nuts also reduces the risk of galling.
