1. Self-Drilling Screws Manufacturers and Suppliers in China
Working on the same principle as drill bits and cutting tools, self-drilling screws allow you to drill into materials such as wood or steel with pre-drilling holes. The flute at the end of the screw allows it to bite into the materials to secure them together. Goldensea offers both off-the-shelf and specially made stainless steel self-drilling screws.
We offer self-drilling screws in many different materials such as steel zinc, 410 stainless, 18-8 stainless. We also offer self-drilling screws with the clinical coating on them. Our sizes start at a #4 and go to 3/8” diameter. We offer self-drilling screws in many different materials such as steel zinc, 410 stainless, 18-8 stainless.

2. What’s the difference between Self-tapping screws and Self-drilling screws?
Self-tapping screws and self-drilling screws are the two primary forms of fasteners that are used in metal buildings or construction of Prefabricated Steel buildings. They also have numerous other applications, and their use isn’t limited to construction either.
Despite the different names, self-drilling screws are just another form of self-tapping screws. Self-tapping screws tap their own threads, but cannot drill through hard objects such as iron, copper, or steel. They also require a pilot hole. On the other hand, self-drilling screws don’t need a pilot hole, and like the self-tapping screws, they can tap their own threads. The self-drilling screw also has higher threads, compared to self-tapping screws. In a nutshell, all self-drilling screws are a form of self-tapping screws, but not all self-tapping screws are self-drilling screws.
These are just like other forms of screws, are available in a variety of specifications, which include:
*Overall built materials (steel, stainless steel, aluminum, brass, or plastic)
*Head type (Philip, Pozi, slot-hex, Torx, square, etc),
*Thread type (coarse or fine)
*Chemical coating/plating (zinc, phosphate, copper, tin, etc)
*Diameter and length.
These are used for their accelerated installation time, which lowers the overall costs and the need of additional equipment. Their excellent fastening efficiency in steel makes them a popular choice for steel frame constructions, or fastening of other materials to steel frames. They can also be used for fastening objects to wood, and are widely utilized for structures such as wooden floors, wooden roof decks, and wooden doors.
