FAQ
Why are self drilling screws made of 410 stainless?
410 stainless can be heat treated hard enough to drill and tap its own hole in steel. It is magnetic and less corrosion resistant than 18-8, so it can show light surface rust in harsh or coastal spots.
Do self drilling screws need a pilot hole?
Not in thin steel. The drill point makes the hole. Match the point to the metal thickness and use a steady, medium speed.
Can I use stainless with zinc plated or galvanized parts?
Use stainless nuts and washers with stainless bolts and screws. In wet conditions, stainless touching zinc plated, galvanized or aluminum parts can cause galvanic corrosion of the zinc or aluminum.
