Carbon steel hexagon slotted nuts, due to their high strength, reliability, and excellent machinability, are widely used in railways, bridges, heavy machinery, power facilities, and other applications requiring extremely secure connections.
The influence of heat treatment process on surface properties is often overlooked. Quenching and tempering parameters directly determine the hardness distribution of the screw matrix.
The cap nut was developed to address these long-standing pain points in engineering practice. Its unique structural design offers significant advantages in preventing loosening and facilitating cleaning.
The cavity size of the rivet head mold must be highly consistent with the designed shape of the rivet head. Excessive deviation will result in an incomplete rivet head contour and a loose fit with the workpiece surface.
Whether a hexagonal nut is suitable for high-strength preload applications is a crucial criterion for assessing its ability to withstand the heavy loads of critical structural connections.
Hollow rivets, with their unique structural design, successfully achieve "single-sided installation," becoming a key fastening solution to address the problem of no reverse working space.
