Knurled Clinch Nut With Blue Nylon Locking Insert

1. Product Introduction

Our knurled clinch nut is a professional thin-plate fastener specially designed for sheet metal assembly. It adopts integrated blue nylon locking insert inside the thread hole, which can effectively avoid loosening caused by long-term vibration, impact and temperature changes.

The outer wall of the nut is designed with uniform knurled teeth. After pressing into thin steel plates, aluminum plates and copper plates, it can form a tight interlocking structure with the plate, without welding, riveting and other processes, and will not fall off under long-term load. The whole nut is treated with hot-dip galvanizing or electro-galvanizing, with excellent rust and corrosion resistance, suitable for indoor and humid outdoor working environments. All internal threads are precisely processed by CNC lathe, with smooth tooth surface and uniform pitch, which can match standard metric screws perfectly.
