Precision ring nuts

Precision ring nuts

Precision ring nuts are manufactured with tight tolerances and radial locking grains so that they can be used when maximum positioning and adjustment accuracy is required.

Precision ring nuts are made out of alloy and hardened and tempered steel. Their support surface is always made during the threading process. The locking grains are made out of brass in order to guarantee the integrity of the shaft during the fixing phase.

The outer surfaces of the ring nut are burnished.
