Bimetallic structure, wide applicability.
双金属结构，适用性广
Yingfeng bi-metal self-drilling screws are high-quality fasteners manufactured by Yingfeng Fastening Systems; leveraging US-standard quality systems and core bi-metal technology, they provide reliable solutions for fastening needs across a wide range of applications.
01. Features a composite structure of 300-series stainless steel and alloy steel, combining high toughness with strong drilling capability; it can easily penetrate 12.7mm-thick iron or aluminum plates.
02. Treated with anti-corrosion coatings (such as Sijiada coating), the product withstands salt spray testing for ≥200 hours without red rust, effectively preventing embrittlement and ensuring a long service life.
03. Compliant with both US and national standards and subject to rigorous quality control, the product offers high strength, high reliability, and excellent compatibility.
ADVANTAGES
Advantages of Composite Self-Drilling Screws
Bimetallic composite
Stainless steel head (corrosion-resistant) + alloy steel tail (high-strength drilling).
Balances performance and cost; resistant to brittle fracture and impact.
