L. H. Dottie No. 12 x 1 1/4 in. Grade 5 Hex Washer Head Self Drilling Screw (100)

Tek 5 Self-Drilling Screws are manufactured from cold-heading steel and feature a 5 drill point. The unique tip design allows them to drill, tap, and fasten metal to metal objects in one operation, without the need to pre-drill. This creates the optimal drill performance and thread forming experience. The most common applications are used on metal to metal, but they can also be used in a wide variety of other applications.
