Pan Head Self-Drilling Screws

Pan Head Self-Drilling Screws are a type of fastener widely used in construction, furniture, billboards and industrial equipment. They have self-drilling and self-tapping functions and can form threaded holes directly on the surface of materials without pre-drilling, thereby improving construction efficiency and reducing material damage.
This product complies with international standards DIN7504N, ISO15481 and ASME/ANSI B18.6.3, ensuring its high quality and reliability. In terms of materials, a variety of options are available, including C1022A carbon steel, SUS410, SUS304 and SUS316 stainless steel, to meet the corrosion resistance requirements in different environments.
The specifications are diverse, ranging from ST3.5 to ST6.3 (metric) and 6# to 1/4" (imperial), suitable for boards and wood of different thicknesses, and can meet various engineering needs. The surface treatment processes are rich, including passivation, galvanizing, nickel plating, blackening, head spraying Dacromet, hot rust and Ruspert, etc. These treatment methods not only improve the anti-corrosion performance of the product, but also enhance the aesthetics and durability.
Whether used in indoor or outdoor environments, pan head self-drilling and self-tapping screws have become one of the indispensable fasteners in the construction and industrial fields due to their excellent performance and diverse specifications. Users can choose the appropriate material, specification and surface treatment method according to specific needs to achieve the best use effect.
