Custom Bi-Metal Self-Drilling Screws
Bimetal self-drilling screws combine a corrosion-resistant stainless steel body with a hardened carbon steel drill point, giving buyers both long-term rust protection and fast drilling performance in metal-to-metal fastening applications.
DISLAB Precision supplies custom bimetal self drilling screws for metal roofing, steel framing, solar mounting, HVAC systems, cladding, facades and industrial construction. The self-drilling point cuts into steel without pre-drilling, while the stainless steel section improves service life in outdoor, coastal and corrosive environments.
Core Product Specifications
Our corrosion resistant self drilling screws can be customized by diameter, length, head style, drive type, coating, washer, packing method and project standard. Whether you need bulk packaging for construction sites or retail boxes for distributors, DISLAB Precision can support OEM requirements and stable repeat supply.

Engineered for Extreme Durability
Dual-material construction gives these stainless steel self-drilling screws the drilling strength of a carbon steel point and the corrosion resistance of stainless steel. The drill point cuts through metal surfaces quickly, reducing installation time and labor cost.
Salt spray performance over 500 hours makes these bimetal screws suitable for outdoor roofing, coastal construction, solar brackets, facade systems and long-term steel assemblies. Hex washer head, flat countersunk, Phillips and Torx options are available to match tools and installation requirements.
Full customization: choose screw length, thread size, head type, coating, bonded washer, drive type, packaging and carton labeling for your project or brand.
