Love spax screws
Love spax screws, very durable, easy to install with a drill and saves time drilling for carriage bolts, washers and nuts. Same strength. I use these when putting A frames together for outdoor swings I build.

Seem to be well made. Haven't yet used them.
Thick. Looking forward to using this type head which seems to be reviewed well by different sites as well.

Tough and lowest price
Extra sturdy and the washer head keeps your screw from sinking through without pulling the boards together like deck screw tend to do. I’m building a barn with them and haven’t regretted using them. Fantastic product for a low price.

Best Structural Screw
Great structural screw for use in treated lumber and composite lumber. I used in building a large deck with composite lumber, has great pullout resistance and corrosion resistance and the washer head holds pieces together tight.

Great Product
I used several hundred of these screws on a small cattle barn and corral I built. They have plenty of holding power. Only one broke and I’m pretty sure that was my fault. Be sure to use with a good impact driver!!
