Zinc Plated Keps K-Lock Nuts
What are zinc plated Keps K-lock nuts? Zinc plated Keps nuts, also called K-lock or washer nuts, are steel hex nuts with an attached free-spinning external-tooth lock washer that locks as the teeth bite the bearing surface. The zinc plating adds corrosion resistance, and the captive washer speeds assembly by combining a nut and lock washer in one economical part.
When to use zinc Keps nuts
Zinc plated Keps nuts are the economical, everyday choice for fast one-piece fastening. The captive washer means nothing to align, drop, or lose, and the external teeth bite the surface for locking and electrical grounding, which is why they are common in electrical panels, motors, and production work. The zinc plating gives corrosion resistance for indoor and general outdoor use. As with all Keps nuts, never over-torque them, since over-tightening flattens the washer teeth and the nut loses its locking action. For wet or coastal use, choose a stainless version.
Why choose zinc plated Keps K-lock nuts
- Economical: cost-effective one-piece locking nut.
- One-piece speed: captive washer means no separate washer to handle.
- Locking and grounding: external teeth bite the surface.
- Zinc plated: added corrosion resistance for indoor and general outdoor use.

Zinc Plated Keps K-Lock Nuts FAQ
What is a Keps nut also called?
A K-lock nut or washer nut. It is a hex nut with an attached free-spinning external-tooth lock washer.
Are zinc Keps nuts good outdoors?
The zinc plating suits indoor and general dry outdoor use. For wet, coastal, or saltwater exposure, choose a stainless Keps nut.
Why should I not over-torque a Keps nut?
Over-tightening flattens the washer teeth, and once flattened the nut loses its locking function. Tighten to the correct torque, no more.
