Crazy Fish –
These things are awesome. Great threads and washer top. Oak was no problem.
I’m building a bar out of oak 3 x 4’s and needed something that would hold them together. These things rock. I predrilled a hole for the head to sink into and these went in without issue at all. There were a few that I moved a bit while testing some joints and they came out and back in without breaking. I did not drill out a hole for the screw at all and they went in. I always like when they include the bit – and it’s good quality. The washer head really brings the wood together into a tight joint, no need to clamp. 50 for about $20 is a great value for such a good wood screw.

Highly recommend -great kit!
Love the kit! Comes with it’s own attachment, I used CHATGPT to tell me which drill bit to use for pre-drilling holes. The screws screwed in with ease.My giant shelf on the wall is still holding! Highly recommend!

Drives smooth 25 torx drivers. No implied warranty on corroosion resistance
Pros:Drives well got the 25 torx not the 22. Came with two drivers extra long and long case is durable should last while using screws.Cons: package does not claim for the osion resistance. They are coated but no expressed or implied warranty against corrosion. Bill di a corrosion test with water and report back if they don’t seem corrosion resistant.

can’t beat the price and function
Nice quality lags. Black finish doesn’t flake off. Self-drill very well. I will buy this brand again.

Great tie in for walls & door header.
Worked great for tieing in a 2 x 4 to the walls and the header for an overhead door. Very solid joint.

Amazon Customer –
Perfect. Just right for putting 4×4 or yard timbers together. Impact driver works the best. They need a fair amount of torque to seat.
