Conical self-aligning boss：The upper conical surface can precisely fit into the corresponding conical hole of the accessory, and during assembly, it can automatically align the center and eliminate eccentricity errors.

Circular stress release groove：A precise groove is set between the frustum and the base. When locked, the conical surface undergoes elastic deformation, enhancing the fit and preventing the base from deforming.

Two-sided usable structure：The front side of the conical part is upward and is used for installing through holes, while the back side with the hexagonal shape is upward and is used for exposing and locking. One piece can meet both types of operations. However

Precise mirror surface polishing：The surface Ra is less than or equal to 0.8 micrometers. It features both aesthetic appeal and easy cleaning properties, and complies with hygiene standards for food and pharmaceutical equipment.

Full through-hole internal thread：The thread runs through the entire height and the connection length is flexible. It supports long bolts to be inserted through from one side and then tightened.

1. The self-centering elimination of assembly error ensures that the conical surface fit has inherent centering characteristics. Even if there is a 0.5mm positional deviation between the bolt and the workpiece hole, after locking, the coaxiality of the mating parts can still be guaranteed at ≤ 0.05mm, eliminating the need for precise alignment time.
2. The conical surface wedge locking anti-loosening mechanism locks by generating radial forces on the conical surface, causing the nut and the workpiece to form a friction wedge locking effect. The conical surface locking thread can resist strong vibration conditions, and its anti-loosening performance exceeds that of ordinary nylon locking nuts.
3. The structural strength is optimized through the design of annular grooves, which enables the conical surface to undergo controllable micro elastic deformation when under force. The stress distribution is uniform, avoiding the risk of stress concentration cracking in traditional integral conical surface nuts, and the fatigue life is increased by more than 3 times.
4. The integration of decorative and functional aspects
When installed externally, the conical surface presents a streamlined metallic texture, which can serve as an aesthetic decorative element; when installed in a blind hole, the hexagonal base is exposed, facilitating tool operation. Both states are both aesthetically pleasing and practical.
5. Clean environment compatibility with stainless steel material + mirror polishing, without the risk of coating detachment, resistant to CIP/SIP cleaning, meeting GMP, FDA-related standards requirements.
