FAQ
Machine screw or sheet metal screw?
A machine screw has a uniform thread made for a nut or a tapped hole. A sheet metal (self tapping) screw has a sharp point and a coarser thread that cuts its own thread in sheet metal, plastic or wood.
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.
Why use stainless deck screws?
Pressure treated lumber eats away zinc coatings, and plain steel leaves black stains in cedar and redwood. Stainless screws won't rust or stain. Use 316 near salt water.
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.
