Hi,
I have a question about using self tapping screws in 304 sheet metal. I originally tried to screw in a self tapper made of 304 stainless steel into 304 stainless steel sheet metal. Of course the screw quickly threaded. I then attempted to use a 316 self tapper into the 304 sheet metal to my supprise allthough harder than the 304 this also failed. I guess this was most likely due to the work hardening that was occuring during the tapping process. Can anyone suggest a material type or self tapping type to over come these problems?
Thanks in advance
roger
