Why do countersunk self tapping screws need a cutting thread?

Mr. Yuan needs countersunk self tapping screws, flat tail, hexagonal slot type, carbon steel plated with environmentally friendly zinc, indicating that he wants the angle of the countersunk head to be 120°.

Generally, the angle of the countersunk self tapping screws is 90°, but the 120° CPT screw manufacturer can also be produced. I also asked Mr. Yuan about the specific product parameters, and what products this screw is used on.

Mr. Yuan gave us the specific parameters, saying that these countersunk self tapping screws are used on the iron plate, and asked if there is any way to increase the self tapping ability of the screw. Then we suggested that Mr. Yuan cut thread self tapping screws of the countersunk head. Cutting thread can increase the self tapping ability of the screw.

 

Mr. Yuan agreed to use the countersunk self tapping screws cutting thread, and then let us give him a price including tax and shipping. After confirming the details of delivery and transportation, Mr. Yuan paid the full payment and let us produce it as soon as possible.
