1) Submitted by Jerry Green, from Phoenix, AZ on 12/16/2011 Customer Rating: These screws are fantastic. I purchased two lengths in #6 & #8. I was so happy a placed another order for more lengths. I drill a pilot hole so the driver does not strip out the screw head. Much less susceptilble to strip out than phillips heads. Self countersinking works well, and is super plus over regular screws. I wish these were available years ago.

2) Submitted by Dana Wilson, from Salt Lake City, UT on 11/13/2010 Customer Rating: I bought #6 Torx screws in 1/2", 5/8", 3/4" and 1" lengths because the brass screws I was using to mount some brass hinges mortised into walnut kept breaking, despite carefully drilled pilot holes. The Torx screws exceeded expectations: strong! self-tapping although I still pre-drilled for my project with a brassy finish that doesn't look bad with the brass hinges. I agree with the other reviewers. This is a terrific product.

3) Submitted by Daniel Kaylor, from Monte Sereno, CA on 3/11/2010 Customer Rating: Exceptionally easy to sink, almost no pilot holes required. These were the best deck screws I've ever used.

4) Submitted by Chris Nelson, from Dry Ridge, KY on 12/11/2009 Customer Rating: After shearing off more than my share of screws I tried these. WOW I am pleased! No more trying to dig out part of a screw in a finished oak piece. I'll tell you they are great!

5) Submitted by Cary Brabble, from Roper, N.C. on 2/9/2009 Customer Rating: Throw away all other screws. This is by far the best I have ever used. The torx head is far superior over phillips or anything else. I have used them without pilot holes and have been very surprised at the lack of splits in my work. I really enjoy using these screws and suggest you try them too.

6) Submitted by Warren Wiley, from Dalton, MN on 3/2/2009 Customer Rating: I am in the process of ridding myself of all the ****** phillips etc. screws I have-and I have plenty!! This is the only screw fellas. Try them once and you'll buy a bunch more. Strong, pull stuff together...you can almost SEE stuff tighten up when these screws go flush, or just below flush. These things are GREAT! And unlike the ##$%@# pot metal phillips head screws we get now these aren't going to chew out on you halfway in. Buy some. Then YOU can write a review like this one!!

7) Submitted by Ken Milhinch, from Melbourne, VICTORIA, AUSTRALIA on 6/14/2010 Customer Rating: Love the screws, hate the drivers. The first one wore out after about 50 screws, and the second one only lasted 3. Granted I was driving into Australian hardwood, but the screws were only 3/4". They seem to be made of a soft metal which is too easily chewed up. 4/21/2011 As a follow up to my previous comments, I have now destroyed two more driver bits. They really need to be made from a stronger metal, especially given the grip they have on the screw head, which leaves no opportunity to slip. On each occasion, I have twisted the tip right off the drivers. Still love the screws though.

8) Submitted by Richard, from Concord, NC on 7/3/2011 Customer Rating: After stripping many Phillip head screws or breaking them off I've been looking for a screw that will work as it's suppose to time after time and a driver that does not strip out the head. I'm a strong believer in this product. I've not experienced the issue with the driver that Ken from Australia notes.

9) Submitted by Mark Kozlowski, from Vancouver, B.C. on 1/4/2009 Customer Rating: ACC proof and very strong. Far more shear resistant than regular screws. The torx head even allows you to drive the screw when you can't get the driver perpendicular to the screw head.
