Product Feature
Optimized Thread Fit: The nut's internal thread has a pre-expanded clearance to ensure smooth screwing and achieve the specified clamping force after hot-dip galvanizing.
Anti-Loosening and Positioning Design: The flange face or conical structure also achieves a uniform zinc layer, without affecting the self-centering function. It can be used with hot-dip galvanized flange nuts or nylon lock nuts.
It has good wear resistance: the hardness of the hot-dip galvanized alloy layer is higher than that of pure zinc, and it still maintains good rust prevention after repeated disassembly and assembly.
