How Can Self-Drilling Screws Reduce Your Metal Assembly Production Time and Costs?

Our ST3.9 self drilling screws eliminate pre-drilling steps entirely, cutting assembly time by up to 40% in metal-to-metal applications. The 6 ribs under head design ensures superior holding power while the self-drilling point penetrates metal sheets efficiently. With C-1022 material construction and flat head finish, you get consistent performance across high-volume production runs. Request technical specifications and samples to test how our drilling fasteners can optimize your manufacturing workflow.

With a minimum order of 100M units per order (USD 5,000), we offer both branded products and buyer's label options to accommodate diverse business requirements. Our comprehensive quality control ensures consistent performance across large production runs, making this self drilling fastener ideal for construction projects, HVAC systems, metal building materials, and industrial equipment assembly. The flat head design provides a flush finish, while the specialized thread design and 6-rib configuration deliver superior pull-out resistance and torque transmission.
