Hard-to-Find Fastener #7 X 2-1/4” Square Drive Trim Head Deck Screws – 305 Stainless, Type 17 Point, 157-Piece

About This Product

Sometimes you just need that specific screw, and this one from Hard-to-Find Fastener fits the bill perfectly.
It’s a #7 diameter, 2-1/4 inches long, with a trim head that takes a #1 square bit.

The material is 305 stainless steel, so it’s got solid corrosion resistance—way better than plain zinc for outdoor or damp applications.

Type 17 point means it self-drills and bites into wood easily without splitting, which is a huge time-saver.
Comes in a 157-piece box, so you’ve got plenty for a deck project, fencing, furniture assembly, or any job where you want a clean, countersunk look with that square drive that won’t strip out like Phillips heads often do.
These are ideal for trim work, cabinetry, or any exposed fastener situation where rust would ruin the look.
Just remember to test them out for your specific use, especially if structural integrity is critical—consult an engineer if you’re building something load-bearing.

But for general home, farm, or shop use, these screws are a reliable choice.

Strong, clean, and made to last.
