4-1/2 Inch Heavy-Duty Outdoor Deck Screws, 50Pcs Star Drive Decking Wood Screws, Rust Resistant Timber Screws for Timber/Log/Landscaping Wood (#14 x 4-1/2" Black)

Built chairs, benches, log holders, etc using these and they work great.

A great screw at a great price. Used on my shed construction to anchor walls to floor.

I needed a strong lag to hold spring loaded farm gates up, but they couldn’t have too thick of a head. These worked great! I’m actually going to suggest these to the manufacturer instead of what they currently supply.

These are fantastic. The quality is amazing and best of all a fraction of the price at home improvement stores

I was surprised how easy it was to install these 8" screws and the flat tops make it easy to mount them flush. The was no end splitting on the edges of 4x6s. However, some of them were not straight and wobbled quite a bit during install - you'll need to hang on. Also, it was obvious that some of the coating was compromised during shipping. I'm not sure how that may impact the life of the screws in pressure treated timbers. Same comments for the 6" screws.

Bought these for a heavy duty work bench. Loved them for that. Then used for rim joist repair on my house after I found some rotten, punky sections. Then used them for securing a board to a 4x4 post so that I can jack the pole in concrete up out of the ground. The one set I used repeatedly took a severe beating during the 6 poles I extracted. They rented when over loading Vice shearing like typical screws.I highly recommend these.

Build dog cover 8x20 ft with 4x4 post.This is about half the price from local big box store for the same quality

These are great screws, they are strong and the t30 drive works great. I used these to install round logs around the top of my wire fence, they can hold a lot of weight and are extremely useful.
