Spax screws are the best, they are well made. Price could be costly, determining the sizing but its worth it. Featuring a T-star head chances of it slipping or stripping out is very rare and how big the head is great, no need for a washer. Also the powerlag threads are incredible, no need for pre-drilling these screws go through wood or stucco like butter. Yet, I have not seen it split any wood(s) so far, its a keeper so far. I use these when repairing wood fences & gates.

    Made it so much easier then lag bolts if you can use these instead. I did not strip any of the torque bit heads out. But I did twist a bit off so I went through 2, T-30 bits. I intsalled about 40 of then in my deck joist I had to repair from rot.
