Abstract:
The present disclosure provides a threaded fastener having a hybrid self-drilling tip or drill tip. The fastener includes a head, a shank connected to and extending from the head, a helical thread formation extending radially outwardly from part of the shank, and a self-drilling tip including a first tapered tip portion and a second tapered tip portion. The first tapered tip portion is connected at a first end to the shank and at a second end to the second tapered tip portion, and the second tapered tip portion terminates in a pointed end. The outer diameters of both tapered portions taper radially inwardly moving in the direction of the pointed end, which renders the fastener suitable for attachment to wood as well as for fastening two metal objects to one another.
