Hello Lewis,
We do not have any in the 5/16, they are all 1/4". The 2-1/2" Long Torx Trailer Floor and Wall Liner Screw for ACQ Treated Wood # TFX250ACQ is the closest thing we have, it gives you the 2 1/2" you are looking for but is 1/4" diameter. The # TFX250ACQ is designed specifically for use with ACQ-treated wood, which makes it a great pick for outdoor or trailer flooring projects where corrosion is a concern. It's made of steel with a special coating that holds up better than standard galvanized finishes against the chemicals in pressure-treated lumber. While not stainless, it offers strong corrosion resistance at a more affordable price point. The Torx drive and Type F point also make it easy to install into tough materials like sheet metal and wood, with a flush finish.
If these will not work for your application I suggest going to your local hardware store like Home Depot or Lowes.

Hey Lewis, did you find the 5/16 deck screws you needed at your local hardware store, or did the 1/4 Torx screws work for your project? I'm curious to know how it turned out, as it could help others with similar needs.
