Threads of Stainless Steel Self Drilling Screws
There are mainly BD thread type and CD thread types for Stainless steel self drill metal screws , the difference between them is that BD threads are the thread of AB thread in self-tapping nails, while CD threads are mechanical thread
BSD type and CSD type screws Introduction
BSD type SS self-drilling screws should have pitch threads as well as different shapes of the end of the drill, drill commonly used No. 2 or No. 3, its design and different plate thickness conditions.
CSD-type 304 316 self-drilling screws, is a machine screw thread, its diameter and pitch of the combination of the approximate uniform thread, the end of the marking for the No. 2 or No. 3, its design type, and different plate thickness conditions.
CSD-type screws do not need to accept the thread measurements, but should be in line with the standard dimensions, generally in those places where the use of machine screw threads than the pitch threads are more advantageous, on the use of CSD-type screws.
