@qewitcofasteners: Hex flange nylon insert lock nut. Not a regular nut. Integrated flange acts as a built-in washer. Nylon ring grips the bolt threads. No washer needed. No glue needed. Just reliable lock. đŠ Where Qewitco lock nuts are used: â Automotive â engine mounts, suspension đ â Industrial machinery â conveyors, compressors đ â Appliances â washing machines, dryers đ â Construction â structural connections đī¸ đ¤ Qewitco cold formers shape flange and nut body in one piece â no welded parts. đą QC checks nylon insert centering and thread fit. Off-center? Won't lock evenly. Reject. The factory truth: A nut that locks without glue or extra washers. Qewitco does both in one. đŠâ #Qewitco #Nylon#Flange#Self#Vibration#SelfLockingNut
