its GRK
I was working on a project to buld a base for a plastic shed and it was just what I needed to secure the 2x8's together. I have had great luck with all GRK fasteners I have used, and will continue to be the only brand I buy.(I have yet to strip out a head on this brand)

    Used to build a boat dock. Great for securing 2x8 joists to header boards before putting in brackets. Also used to hold 2x4 railing system on a gangway. Love the way these suck the boards together!

    Bite well.
    Screws bite well and are holding up a lot of garage shelving (plus a roof hoist for my jeep) well.

      Quality is rated by durability. I have no idea how well this product will last, but I will say they went into the wood just fine. I do think they are overpriced
