SPAX4581820701555 1/4 x 4-1/2" T-Star Drive Washer Head Black HCR (High Corrosion Resistant) (Exterior) Powerlag Screw (50 Pieces per Box)

For an owner-builder like myself the availability of this first rate product in quantity is great. It hasn't been that long since easy to use structural screws have been available for framing.

I used these for securing deck framing boards to posts. They drive in very easily with an impact driver and the supplied bit. I highly recommend them and will use them again on other projects.

as advertised

Received them when they said. Star bit came with them which was great. Used them building a foundation for sheds with lumber that was ground contact treated. My home improvement store only had them individually...not good when you have a project to do. Bought a total of 3 boxes.

I bought these to install my window guards, I really liked the four and a half inch length the black color and the fact that they have a welded washer attached to them.

I’m using these for wall mount TV brackets. Perfect application for a strong screw with this larger washer style head. USA made, quality.Toss the junk screws that come with the TV mount and use these.

Good quality, good price. They are used in construction and help hold boards in place and secure.

These are great brand-name screws that hold very well. I have used them in all sorts of construction projects. They drive in quickly and hold very well. They are quite a timesaver where they’re building a deck or anything else outdoors.
