These Norwesco self-tapping screws (SKU N-63870) are a steel fastener accessory for tank installation and fitting work, not a storage vessel. Each is a small steel self-tapping screw from the Norwesco accessory line. If you found this while searching for a "norwesco tank" fastener or mounting hardware, this is the item that pairs with Norwesco equipment during install.
What it does
Self-tapping screws cut their own mating threads as they are driven, so you can fasten brackets, straps, labels, or accessory hardware without pre-tapping every hole. This item is steel construction (product application: Self-Tapping Screws). The pack lists no gauge, length, thread type, drive, or coating, and it carries no capacity, resin, or specific-gravity rating because those fields apply to tanks, not fasteners. Treat this strictly as installation hardware; the tank itself governs any chemical or potable-service decision, never the screw.
Confirm size and count before ordering
The catalog dimensional and weight fields on this hardware line are placeholder values, not measured specs for a single screw. Before you order, confirm the screw size and the pack count by phone so you get the right fastener for your bracket or strap. If you are still deciding on the tank these screws support, size the vessel first and let the mounting hardware follow. Our Tank Sizing Calculator and Tank Sizing Guide walk you through capacity and footprint before you commit to mounting details, which keeps you from buying accessory hardware for a tank that turns out to be the wrong size.
Freight and how to order
This accessory ships from the Norwesco plant in Sheldon, IA. Freight moves LTL and is quoted live to your ZIP rather than bundled into the list price, but a small bag of screws rarely ships on its own — the practical path is to combine it with your tank order. Run your delivery cost through the Freight Cost Estimator, or call 866-418-1777 and we will confirm the right screw size and count and roll it in with your tank so you are not paying separate freight on hardware. If you are unsure whether these screws match your Norwesco setup, give us the tank model on the phone and we will verify before you buy.
