Thread rolling raised cheese head screws

Describe

The threads of pan head triangular lock screws are triangular in shape, which is different from the threads of traditional screws. This special thread requires a special triangular screwdriver or tool, making it difficult to tighten or remove with normal tools. For long-term safety, pan head triangular lock screws are usually made of corrosion-resistant materials such as stainless steel or galvanized carbon steel.
