Used to use to anchor a floating ceiling medallion to the ceiling. They are “self tapping” so no pilot hole is needed once you mark your studs. Quality fastener for heavy duty needs.

Holy cow these babies know how to screw into the 4x4‘s we used to build the hen house base. Self tapping and snugged it together perfectly. The t30 bit didn’t slip at all. Superior product to keep it together.

I used two to mount a BMW wheel on the wall of my garage. I pobably only needed one as i coud do chin ups on it! I tried to remove the coating with a wire wheel to get it silver but had to use a sanding wheel. Looks like it would hold up to the elements outside.

So much better then a lag bolt. With the torx head this goes in very easy with a cordless screw driver. We use this in place of the old style bolt head lag bolt. You can't go wrong with this screw and brand.

Best fasteners available. If you had a wider selection, I wouldn’t have to go to other hardware stores

These high grade steel screws take all the torque you can give them. They are self-tapping and extremely sharp. The broad heads provide great joining force and a positive stop without sinking into the wood.

Strip and Bend
I had several these start to bend and fold under slight pressure. Driving thgh 2 3 4x4's they only made it through 1 and a half before bending or having the head strip out. I purchased new Miluakees star heads to do this job. Very dissapointed.

These structural screws are about the best thing you can use. I use my impact drill and they will secure anything
