Strong and reliable

4 days ago
Strong and dependable screw. Great for structural integrity. The stainless steel finish means this screw will hold for a long time. Used this on a deck and concrete brace and it held with no issue

Work well, bit included, and would use again.

4 days ago
These construction wood screws worked great for building this patio plant holder/ bench! They are obviously a great material and hold up to the weather, but they were great for fastening the wood planks together. I appreciate the included bit in the box. And overall didn’t add any excess weight compared to any other brand of screw I have used in the past.

Very durable

These screws are extremely durable, have a great thread for pulling my wood projects together, and was very easy to use with the bit that comes with them. I would highly recommend to anyone.

Reliable, high quality, screw you need for many projects

16 days ago
These are great screws. Been using SPAX for awhile. While pricier than other brands, SPAX screws are very high quality. They have sharp tip, makes it easier and smoother to drive it in. They are stainless steel so they won’t rust. They grip and hold well. I haven’t had one screw break yet even when I had to remove and drive it back in. They are perfect for holding wood together and can be used in so many projects. Their length, shape of the screw head (it goes in flash with the surface, or can be left sticking out to hand a planter, seasonal decor, bird feeder or something similar) are perfect for variety of projects. Pretty much if you need to screw wood to wood, these screws are perfect. Great to always have on hand for this very reason.
