I'm looking for some screws for use in production work.
*Sick of tapping lots of M4 and M4 holes. *Used for attaching small brackets and DIN rail etc. *Fixing to to mild steel 3mm thick or to 1.6mm thick Zinc Anneal sheet.I've seen screws like in the links below but am having trouble finding them. When I look for self tapping screws I find the coarse thread type rather than the defined M4x0.7 or M5x0.8 threads.
Is there a proper name for these screws:
Thanks.
