Here's how a conical safe nut might work

1. Conical Shape: The nut has a tapered shape, with the diameter decreasing towards one end. This allows it to be wedged tightly against the bolt or stud it's threaded onto.

2. Locking Mechanism: The nut may include a locking mechanism such as a nylon insert, which is a ring of nylon material inside the nut's threads. When the nut is tightened onto the bolt, the nylon insert is compressed against the threads, creating friction that helps prevent loosening.

3. Metal Locking Features: Some conical nuts may feature metal locking mechanisms instead of or in addition to nylon inserts. These could include serrations or other designs on the nut's threads that bite into the mating surface when tightened, or separate locking elements like locking clips or tabs.

4. High-Quality Material: Conical safe nuts are typically made from high-quality materials such as stainless steel or hardened steel to ensure durability and reliability in demanding applications.

These nuts are commonly used in machinery, automotive applications, aerospace, and other industries where vibration or torque could cause traditional nuts to come loose over time. Their design helps to maintain a secure connection between components, reducing the risk of equipment failure or safety hazards.
