PLEASE NOTE: QNM 12002 is a new part number which denotes a change in pilot diameter "E" as shown.
The metric QNM weld nut has four identical precision projections. They are positioned and designed to fuse simultaneously so each projection flows and seats properly for maximum weld strength. The four projections provide additional weld area coverage with maximum strength. The pilot on the QNM weld nut provides additional thread engagement and prevents any possible shunting of the projections onto the threads. This eliminates the necessity of retapping filled threads.
