Recently, a customer asked if wood screws and self-tapping screws are the same. Just taking advantage of this opportunity, xxx will talk to you about the difference between wood screws and self-tapping screws.

1. Wood screws are similar to machine screws. They can be directly screwed into wooden components to fasten a metal (or non-metal) component with a through hole to a wood. This connection It also belongs to the detachable connection. Wood screws have low strength and can only be screwed in relatively hard places. Commonly used wood screws have a diameter of about 2.5-4mm. There is no matching screw cap. Use it with a flat-head or Phillips screwdriver.

2. Self-tapping screws are used for non-metallic or softer metals and do not need to drill. Mainly used for the connection and fixing of some thinner plate parts, such as the connection of color steel plate and color steel plate, the connection of wall beams, etc. Self-tapping screws are usually exposed outdoors and have strong corrosion resistance.

Although these two screws are similar in some aspects, there are still differences:

A. Self-tapping screws need manual operation, and the screws are small and the scope of use is also limited.

B. Self-tapping screws have high hardness, wide thread spacing, deep thread, and uneven surface.

C. Wood screws have no threads at the back end, and the threads are thin, sharp and soft, while self-tapping screws have thick threads, sharp and hard.

The above points are the difference between wood screws and self-tapping screws, I hope they can be helpful to everyone. When you order screws, you still have to choose suitable screws according to your own usage scenarios.
