    Ive always hated the normal nails and screws you find at Home Depot and Lowes. These things from FastenMaster are definitely the way to go. There is no need to predrill holes and they really bite into the wood. I love them!

    Although they are a bit Pricey, they are without a doubt the best holding screws Ive ever used and I have used them all. They go in rather easily , draw up tightly and hold like the wood was welded. Great Product!

    What can I say? They are fasteners.

    There where quite a few missing the threads in the bucket. Probably A dozen or more.

    Used to build a deck, these things literally saved the day, Ill continue to purchase these for any large wood project that I have to work on where full support is needed/required (deck footers/stairs/railing). Awesome product at a decent price (fairly expensive, but time saving).
