Screws

You can measure a screw in inches from the tip to where the screw head rests to get the length.

We have different materials of screws on offer, such as wood screws, sheet metal screws, roundhead screws, machine screws and lag screws.

We have a wide range of different deck screws, which all come in different sizes. To know which size the deck screws are, you need the gauge, length, and thread size. The gauge is the diameter of the screw. The higher the gauge, the larger the screw. For deck screw, you are likely looking at either 8- or 10-gauge screws. To be specific, 8 gauge roughly equals a diameter of 4mm. A common rule of thumb for the length of a screw is that a screw needs to go at least halfway into the wood beneath the piece you are attaching. But when attaching deck boards into joists, a 2.5” deck screw is usually long enough since over half the screw is buried in the joist. For the thread size, screws that are wood, deck or multi-purpose and rated for treated-wood use are going to have a similar thread size.
