01
Rust-proof & Corrosion-resistant Stainless Steel Material
Made of AISI 304 stainless steel (A2-70). High chromium content forms a dense passivation film, preventing rust in humid, salt-spray, outdoor, or chemical environments. No plating needed – retains natural metallic luster. Ideal for marine equipment, outdoor furniture, and bathroom assembly. Even after long-term exposure to rain or high humidity, it stays bright, eliminating disassembly difficulties and connection failure caused by corrosion.
01
Metal Material for Tightening & Anti-Loosening
304 stainless steel offers tensile strength ≥700MPa. The self-tapping sharp thread bites tightly into sheet metal, plastic, or wood, creating an internal thread locking effect. The large pan head increases bearing area, preventing thin material deformation or indentation. Metal material never ages or becomes brittle, maintaining stable clamping force under vibration or temperature changes – ensuring lasting, reliable connections without extra lock washers.
01
Long Service Life with High Wear Resistance
Stainless steel substrate with passivation offers high hardness and no plating peeling risk. The Phillips drive and large pan head reduce tool slippage; the self-tapping thread resists wear during repeated assembly/disassembly. Proven in durability tests, this product performs long-term in high-vibration or frequent-maintenance applications (e.g., appliance housings, vehicle interiors) – resisting thread stripping or wear, greatly reducing replacement frequency and maintenance costs.

Lab for Innovation:
Do you currently have any initiatives underway? Now let's get started. Talent and hard work drive our success, and we're constantly searching for fresh ideas. Do you currently work on a project? Now let's get started.
Throughout the whole collaborative research and development process, from "Pain Point Diagnosis" to "Customized Implementation"
We provide more than just standard parts. Our multicultural engineering staff actively participates in your project from the outset. To ensure that creative concepts are swiftly translated into workable solutions that lower total lifecycle costs, we carefully evaluate the application environment and create solutions in the lab, fully integrating technology and application.
Integrated Verification System: Assuring Innovation with "Test Data"
The drawing board is not the end of the creative process. Through our internal technical center, we provide one-stop verification for anything from corrosion testing to prototype creation. Through thorough simulated working condition tests, we use empirical data to confirm the performance stability of tailored solutions. This significantly reduces project risks in addition to generating truly reliable cost reduction and efficiency improvement.
