Stainless screws, nuts, or bolts are required on duct supports
Use the stainless hardware type/grade required by the project, not just whatever stainless is on the cart. Stainless fasteners can gall or seize, so use the approved anti-seize/thread lubricant when directed.
Stop if Ask when stainless hardware is required, threads begin to seize, hardware is mixed with other metals, or the support detail is not clear. Watch out Do not dry-run stainless threads under load, force cross-threaded hardware, or assume anti-seize makes the assembly corrosion-proof. Check Verify stainless grade/type if listed Keep nuts/bolts/washers matched to the approved detail Hand-start threads cleanly Apply approved anti-seize if required Tighten without using the bolt to pull bad alignment together Ask before mixing stainless with aluminum, galvanized, or coated parts. Steps Verify stainless grade/type if listed Keep nuts/bolts/washers matched to the approved detail Hand-start threads cleanly Apply approved anti-seize if required Tighten without using the bolt to pull bad alignment together Ask before mixing stainless with aluminum, galvanized, or coated parts. Say this to your foreman Do you want stainless hardware here, what grade/type is required, and should I use approved anti-seize before tightening?
