Hey guys, I was giving this big big container of screws and fasterners that some dumbass contractors left on a deck at my significant others house so I was able to take them. They are mostly regular deckscrews, but a few of these extra long, gold colored screws with an unusual head and bit required. What is the purpose of these compared to regular screws? Thanks!

I think they are for screwing landscape timbers together.

its a truss head screw, used in cabinet building and other builds, large washer type head gives great grab and pressure, one sometims has to be careful if using power torque driver to not strip unit, quite a few come with the ddrill head to ease install

I concur and used similar to these recently. Torx heads don’t cam out when using an impact driver.

The Contractor would have likely remembered to pack those screws back on the truck as he paid for them. Employees can get in a hurry and fail to walk the jobsite one final time to check for items missed. Ask me how I know. I go to jobsites and find boxes of wire, step ladders and other items left behind. Probably buy 10 Kline 10 in one screwdrivers a year for employees’ that already have them. Got to the office at 8:00 AM and the van was idling in the lot I turned it off. Employee didn’t leave until 8:40, oh I might add that I am wearing short sleeves today.

Assuming the deck is connected to the house, these were most likely used to attach the deck ledger board to the house rim joist.

Yes, structural screws and expensive. A quick browse through your local big box “borg” center would show you all kinds of fancy screws. Worth the time as you can find out all things that are not obvious.

I don’t do decks anymore but they used to be bolt thru into rim joist. Current code here is for deck to be free standing and not attached to house
