Stainless Steel Wood Decking Screws
Self-tapping screws are threaded fasteners that are self-tapping in the pre-drilled holes of metal or non-metal materials.High-strength, single-piece, single-sided combination. Due to its self-forming or tapping its matching thread, it has high anti-loose ability in combination and can be loaded and unloaded. Its size, thread type and head on small screws Type and tapping performance are almost limitless in engineering applications.
Self-tapping screws are said: the holes of the drill are holes that do not need to be tapped. The screws used are different from the general ones. The head is pointed and the teeth are relatively large. It is similar to the chipless tapping. It can be directly screwed in without tapping. Metals and plastics usually use this method.
It can "tapping-drilling, squeezing, pressing" the corresponding threads on the consolidated material by its own thread to make it fit closely to each other.
