Stainless Steel Keps K-Lock Nuts
What are Keps K-lock nuts? Stainless steel Keps nuts, also called K-lock nuts, are hex nuts with an attached free-spinning lock washer that speeds assembly while resisting loosening. Made from 304 stainless and A2 metric, they resist rust and combine a nut and washer into one part for fast, corrosion-resistant fastening.
Why Keps nuts speed up assembly
Because the lock washer is captive on the nut, there is no separate washer to align, drop, or forget. That makes Keps nuts a favorite in electrical panels, motors, and production assembly where speed and reliable ground contact matter. The external-tooth washer bites the surface for light locking and grounding. They suit lighter-duty vibration; for heavy vibration a nylon insert or all-metal lock nut holds better. Match the grade with A2 comparable to 304.
Why choose stainless steel Keps K-lock nuts
- One-piece speed: captive washer means no separate washer to handle.
- Light locking: washer teeth bite the surface to resist loosening.
- Grounding contact: toothed washer suits electrical connections.
- Corrosion resistance: 304 and A2 hold up in wet and outdoor use.
Common applications for Keps K-lock nuts
- Electrical panels and enclosures
- Motors and appliances
- Production and repetitive assembly
- Outdoor electrical hardware
