Heads Strip Out

Would Not Recommend

Overall the screws are a great idea and when you can get them driven all the way in they work great. But getting them screwed all the way in is a challenge. My project required 6 screws. They first 2 went in great but then the wheels fell off. The next 2 screws made it in and I needed about 3 revolutions to seat it and the screw heads stripped out. I couldn't drive them down or back them out. So when I got done I used 9 screws to get 6 set and there are 3 that are still raised. You would think t...

Works as expected

Would Recommend

Does a great job, I used these to secure handrails through a 4x4. I drilled a 3/16" pilot hole and countersunk the hole just about 1/8" with a 5/8" paddle bit and it made a nice, flush appearance. Expensive, but appears to be of good quality. Also nice that they include the T40 bit needed to drive these.

Good as expected

They're screws and they no the job. We'll see how they hold up over time outdoors. Used to make a wooden gate.

Good, but Check the Drive

Would Recommend

These are well designed and quality screws - BUT, check the drive that comes in the pack. The drive in the pack I bought was too small, and the screws don't take the standard star drives. So open it up, pull out a screw and the drive and ensure the match!!!!

Better than lag bolts

Would Recommend

I used these to anchor a railing to our deck and was I impressed..... I did pre-drill the rail but not the deck supports I anchored to they drove right in with my 20V drill/driver. With the countersink they look better than lag bolts and it sure seems they are a lot more sturdy than lag bolts. Time will tell but so far I highly recommend these screws!

Great screws, just buy extra

Would Recommend

Bought a 12 pack and one was bent at a 30 degree angle when I opened the container. They work great at putting together larger wood products. Make sure you have a good drill because it takes a decent drill to get these puppies installed all the way.
