Zinc Plated Self Tapping Screw | Custom OEM Fasteners

A Zinc Plated Self Tapping Screw is a versatile fastening solution that forms its own mating threads as it is driven into a pilot hole, eliminating the need for nuts or pre-tapped threads. This makes it ideal for high-volume assembly where speed and reliability matter. The zinc plating acts as a sacrificial barrier, protecting the base steel from oxidation and extending service life in humid, marine, and outdoor conditions. For international buyers, the key value lies in consistency: thread pitch, core hardness, and plating thickness must remain stable lot to lot to prevent stripping, cross-threading, or premature corrosion. Our company addresses this through integrated forging, cold heading, CNC machining, and controlled surface treatment. With 8 forging machines, 10 multi-station cold heading machines, over 100 CNC lathes, 50 machining centers, and 20 turning-milling composite machines, we can produce both standard and non-standard Zinc Plated Self Tapping Screws with tight tolerances. We also consider cultural and regional requirements, such as RoHS compliance, packaging preferences, and documentation standards, so customers in Europe, North America, and Asia receive products that fit their market. Whether you need a self-drilling point for sheet metal or a fine thread for plastics, our engineering team can recommend the right geometry and plating specification to reduce assembly defects and total cost of ownership.
