    3. Self Drilling Screw Selection Guide:

             

          

    Drill Flute

    The length of the drill flute determines the metal thickness that can be drilled. The flute itself provides a channel

    for chip removal during drilling action. If it becomes completely imbedded in material, drill chips will be trapped in the flute and cutting action will cease. This will cause the point to burn up or break

     

    Point Length

    The unthreaded section from the point to the first thread should be long enough to assure the drilling action is

    complete before the first thread engages the drilled metal. Screw threads advance at a rate of up to ten times faster

    than the drill flute can remove metal. All drilling therefore should be complete before threads begin to form.

     

    Drilling Through Wood To Metal

    If your application calls for drilling through wood over 1/2" in thickness, a clearance hole is required. Select a fastener with break away wings for this type of job. The wings will ream a clearance hole and break-off when in contact with metal surface (minimum metal thickness .090") to be drilled.
