Dimex EasyFlex Galvanized Metal Deck and Dock Screws, 100 Count, 1-1/4 -Inch Length (1960-100-6)

Great product! These screws are so tough, we actually had them on a thinner wood piece and they actually went through the wood and a little more than a 1/4 of an inch inside the concrete beam of the dock. I would really recommend these for marine use.

These are overpriced concrete screws to secure celemt backer board under tile floors.. Spent $14 on 100 when I could get them at local big box store for $7 or 8. Then I needed to get a washer so the screws don't dig through the rubber dock edging. I'd suggest looking for a screw with a build in flange head washer like a cabinet screw..

Installed easily through the Dimex P-Profile dock edging and into dock boards. A sightly wider head would be nice to prevent going through the edging, but got the job done.

These are insanely sharp, but do a nice job attaching the Dimex dock bumpers. They drove in very very easily. Nice product

Worked perfect for attaching bumpers to our dock.
