Zhuocheng Self-Clinching Top Collar Lock Nuts

The design of the self clinching top collar locking nuts, provide a simple means of installation whereby the self clinching lock nut is placed into a pre-punched hole in the panel and when the squeezing force is applied the clinch nut becomes an integral part of the chassis. The basic premise for the proper installation of the clinch nuts is that the fasteners must be harder than the panel into which they will be installed. The clinch fasteners also need to be installed into ductile materials such as steel, aluminum, or copper panels. The maximum recommended hardness is HRB 70. The self clinching top collar locking nuts offer a nylon locking feature, which is often desired in a design that may be subject to vibration, which may cause the mating screw to disengage from the nut. The locking feature can prevent the mating screw from backing out and possibly shorting out the electronic unit.
