Red Hound Auto 80 Piece Truss Head Screw Set for Dock Bumper Installation Marine Grade Stainless Steel 10 x 1-1/4 Inches SS

Checked with a magnet- not magnetic, beyond that induced by cold work from forming the screw. Even that is almost imperceptible. Appears to be a good product. Installation tip-- there are several comments about these being soft and easy to strip out. Well, they are. But that is their nature. It is not a defect. These are 300 series stainless steel. This material is used for its corrosion resistance, not its strength. They cannot be hardened like tool steels, or other high strength steels. They are intentionally sold in their softest (annealed) condition because that is where the corrosion resistance is at its best. So pilot drill your holes, and press hard on the driver and make sure your driver is not tipped off at an angle when driving. If you use a drill, set the torque limiter to the minimum necessary for your set up (test it in a scrap piece!). With this size stainless screw, most electric drills can rip the heads right off if over torqued. And if you tip off at an angle, you can easily strip the head. So I hope this helps. Good luck!

Rust after 6 months!! Crap. Want my money back!!

It’s worth the extra money to buy these screws for my Marina needs

As advertised 5 Star *****

I wish they’d make torque screws instead of Phillips because the screw is easy to strip out if your not perfect lining up when you screw it in. Other than that they’re good
