Product Description

This type of Dual Function Crown Nut With Slot looks very unique. Its bottom is hexagonal - thus it can be operated with an ordinary wrench - and the top is dome-shaped.

The dome part has several slots (usually six), which are evenly distributed and extend straight along the axis of the nut. These slots are precisely machined and can perfectly match standard open pins. The design of this slotted round head nut is both practical and safety-oriented: once you tighten the nut, it can be fixed in place, thus preventing it from falling off from the bolt due to vibration or other forces.
