About 1 1/2 years ago I built a deck outside my tool shed. Yesterday I noticed one of the 5/4 TYP deck boards was popped loose at the end. I first thought sloppy screwing would be the blame but on inspection I see the 2 – 2 1/2″ deck screws are broken slick off just below the deck board.
I’m often amazed at the warping potential of SYP boards but I’d never expected it would be sufficient to snap off the screws. But then again I don’t know what Grip rite rates the shear of their deck screws at, it’s not on any specs I’ve seen at their site.
It’s an easy fix but I hope this is a cautionary tale to people who put such screws to load bearing applications.
