Trilobular Screw

Trilobular thread rolling screws form threads in drilled, punched or cored holes in ductile metals and castings.Trilobular screws are the leap forward in high production assembly using threaded fasteners. Trilobular fasteners roll-form threads as they are driven, eliminating expensive tapping operations.Trilobular screws represent the refinement of the TRILOBULAR principle for specific demanding applications. Its unique tri-lobular configuration provides a built-in locking device to help ensure joint integrity. Consequently, resistance to vibration loosening is improved without add-on locking devices.Trilobular screws have generous lobulation at the screw point for easy entry and optimum thread forming action plus reduced lobulation in the screw body holding area. A stabilizing threaded dog point insures ready, aligned entry, with easy pick-up requiring minimal starting end load.
