Minerallac 72960J – Frequently Asked Questions

1) Will a #9 x 2-1/2 inch deck screw hold composite decking down to the joists, or do I need a composite-specific screw?
The Minerallac 72960J deck screw is made for exactly that job: fastening treated wood and composite decking to the main beams. At #9 gauge by 2-1/2 inches, it has enough length to pass through a nominal deck board and still bite well into the framing below. The flat head seats flush with the deck surface rather than standing proud of it.
2) What driver bit do I need for Minerallac 72960J deck screws?
They take a combination Phillips/square drive head, so either a #2 Phillips or a square drive bit will turn them. The square drive is the one to use if you are running a lot of them off an impact driver, since it cuts down on cam-out.
3) Is 2-1/2 inches long enough for a deck screw, or should I go longer?
For standard 1 inch nominal deck boards (5/4 or 1x material) going into dimensional joists, 2-1/2 inches is the common length and is what the Minerallac 72960J is built around: decking fastened down to the main beams. If you are fastening thicker stock, a 2x laid flat, or doubling boards, you want a longer screw instead, since 2-1/2 inches would leave too little thread in the framing.
4) Can I use these screws for framing or structural connections?
No. The 72960J is a decking fastener, intended for attaching treated wood and composite deck boards to the beams below. Structural connections, joist hangers, and ledger attachment call for fasteners rated for that use. Keep these for the deck surface.
5) Do these deck screws work in pressure-treated lumber?
Yes, treated lumber is one of the two materials called out for this screw, alongside composite decking. Minerallac lists pressure-treated installations as an intended application.
6) What is the part number to order Minerallac deck screws in the #9 x 2-1/2 inch size?
Order Minerallac model 72960J. It is a single model, #9 diameter by 2-1/2 inches long, Phillips/square drive flat head. Country of origin is Taiwan.
