Answer This Question

A:  This is a decking screw intended for use with all treated lumber and exterior projects for wood-to-wood applications.

A:  No, Nails are much stronger especially in sheer strength. Screws work best for holding down deck boards and similar applications.

    Answer This Question

    A:  A screw cap is used to cover the screw ends when drilled. Whether to buy them is personal asthetic preferences. The screw will work good without them.

    Not packed correctly for shipping!
    Had many “loose screws” due to the pail being shipped UPS and not packed with bubble wrap in the box! We assumed it would come with the deck lumber and not via UPS!

      The poor review is due to the fact that ALL of the screws were 2 1/2 inches. I purchased the screws to repair my deck and the closest Home Depot is an hour away from my home where the 3-inch screws were to be used to repair my deck. The poor report is not for Home Depot, rather the POOR QUALITY CONTROL from their supplier "Deck Mate". Should I purchase any "Deck Mate" product again, I will be verifying the product before leaving the store.

      Screws are excellent. Packaging was damaged as if it had been dropped and then taped up. I did not weigh the item and I am inclined to believe that all the contents were there but I believe that I should have been informed of the condition of the container and given the option to refuse that particular package.
