    Awesome Screws and love the large washer type head on them. Only wish the t-star was deeper to get a better connection. Had some issues with the head stripping out but not very often. Deeper opening would help.

    These screws are mean, they will go through iron wood like butter. And the have great suck up capability. They have broken on me a few times but that is drilling through Ohia or Koa wood.

    A very good fastener. No need for pre drilliing. I just used it to a regular wood though. I assume that it will perform the same way in hardwoods.
