TAPTITE® thread rolling screws form threads in drilled, punched or cored holes in ductile metals and castings.
TAPTITE® fasteners roll-form threads as they are driven, eliminating expensive tapping operations. The TAPTITE® fastener's 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.
