Next: DIN 7967 Counter Nut (Pal Nuts) 
Prev: Castle Nuts (DIN 935) 
A Cleveloc Nut is a self-locking nut with quality re-usability characteristics and superior locking. It holds a geometrically developed elliptical collar to provide flexible locking. This elliptical form ensures a high fatigue life and consistent performance, as well as dependability in service.
Each thread within the nut body is free running, and is easily engaged with either a spanner or power tool able to tighten the nut.
The stress within the locking device is distributed, allowing for a number of uses and extended service life.
The Cleveloc Nut is Manufactured in a range of materials, with specials also available.
Available at Fastenright in thread sizes M4 to M30 as standard, with other sizes available to order.
Non-standard sizes, materials and finishes are available to order as specials, including small volume manufacture, modifications and bespoke parts made to drawings. Minimum order quantities apply.
