Strong and reliable

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.

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.

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.
