Self-Drilling Screws
Self-Drilling Screws
(OP)
Buenas Dias![smile] Could anyone provide me information on the pros & cons of Self-Drilling Screws? We have this case wherein a frame is supported at two points. At these two points, the fixing is proposed to be fastened on a 6mm thk steel RHS using Self-Drilling Screws, for installation convenience. From my understanding, frames or trusses are fixed though a welded or bolted connection. This is the first time I have encountered such case. Help![dazed]

You will see in the literature that the FOS for the screws is pretty high for obvious reasons.

I have no issues in terms of the allowable values. It's just that every time I analyse these fasteners, it's for light loading only. I'm just worried that I may have overlooked a few points when considering self-drilling screws. Won't there be any problem in installation? Is it really okay to fix it at a 6mm thick steel? What if for some reason, the frame should be removed, and it is needed to unscrew the fasteners, and put back again, would there be any complications?
