Description
The Whittet-Higgins CNF Series Clamp Nuts are precision-engineered, single-point self-locking nuts designed to securely position and retain bearings, gears, pulleys, and other components on threaded shafts. Utilizing a radial clamping action, the CNF series delivers reliable holding power without damaging shaft threads, eliminating the need for lock washers, tab washers, or keyways. Manufactured from low carbon steel and finished with a black oxide and wax coating for corrosion resistance, these clamp nuts are ideal for low to medium speed applications where vibration, shock, and torque could cause loosening. The CNF series offers infinite adjustment and accurate preload control, making installation faster, easier, and more repeatable while ensuring long-term performance in demanding industrial environments.
