I've got an aluminum pole set consisting of multiple segments that need to be connected together to form one long pole using self-drilling and tapping SS screws. I've never used this type of screw and I am unfamiliar with how I should proceed. The directions that came with the product are very vague about what I should do, saying only:
"You will use a series of pre-drilled holes, spaced approximately 1-1/2" and 7-1/2" inches from each end, to join the large tubing to the small tubing. These holes are space 120 degrees apart. At the appropriate time you will secure with self-drilling and tapping SS screws."
The pre-drilled holes are very small, much smaller than the width of the screws, which appear to have a rather wide tip unlike a normal screw which has a sharp tip, so I'm not sure how I am supposed to get the screw to engage with the hole. Furthermore, there is no slot to put the screwdriver or drill bit into the screw, so I'm not sure how I'm even supposed to drive it.
