Our black coated 410 stainless steel Phillips pan head self‑drilling Tek screws are manufactured from 410 stainless steel (hardness HV 400‑500) or medium‑carbon steel (Grade 8.8‑10.9), with an eco‑friendly black zinc or black oxide coating that combines corrosion resistance with a matte, low‑profile aesthetic. The hardened self‑drilling point penetrates light‑gauge steel studs, electrical enclosure sheet metal, and thin‑walled steel sections directly – no pre‑drilling required – completing drilling, tapping, and fastening in one operation. The Phillips pan head design is compatible with standard screwdrivers and power tools, and the smooth underside of the pan head prevents damage to the workpiece surface. The anti‑slip, high‑grip self‑tapping threads ensure secure fastening in metal, wood, and plastics. Sizes M4.2‑M6.3 (#8‑#14), lengths 13‑150mm custom. Ideal for light steel stud ceilings, black sheet metal equipment, automotive interior modifications, metal‑wood hybrid assemblies, and minimalist furniture/lighting installations. Installation: drive directly with an electric drill or impact driver – the drill point creates the hole, and the pan head seats flush.

Dual-Material Options – 410 SS for Hardness or Carbon Steel for Cost Efficiency
Available in 410 stainless steel (HV 400-500, high torque for heavy metal penetration, wear-resistant tip) or medium carbon steel (Grade 8.8-10.9, reliable strength with cost optimization). 410 grade penetrates light-gauge steel and sheet metal without tip breakage; carbon steel with black oxide coating offers durability and economy. Dual materials cover various project budgets and conditions – one screw for both premium and general assembly.

Black Zinc/Black Oxide Coating – Matte Corrosion Protection & Stealth Aesthetics
Finished with eco-friendly black zinc or black oxide, delivering a uniform matte black finish that effectively resists moisture, salt spray, and industrial corrosion. Strong adhesion with no chipping or peeling – color stays stable and rust-free outdoors. The dark appearance seamlessly blends with black sheet metal enclosures, modern minimalist furniture, and automotive interiors – no secondary painting needed, combining functionality with design.

Phillips Pan Head + Hardened Self-Drilling Tip – One-Step Fastening, Flush & Anti-Loosening
The Phillips pan head fits standard screwdrivers and power tools, delivering high torque without cam-out; the smooth pan head underside prevents surface damage. The hardened self-drilling tip completes drilling, tapping, and fastening in one step – no pre-drilling needed for high efficiency. Anti-slip high-bite threads securely grip metal, wood, and plastic – resisting vibration and loosening. Durability-tested for long-term load retention without shifting – ideal for light-gauge ceiling framing, furniture/lighting assembly, and automotive modifications.

Innovation Lab:
Expertise and collaboration drive us forward, constantly pursuing innovative solutions. Have a project? Let's get started.
"Customized Implementation" to "Pain Point Diagnosis" in the Entire Joint R&D Process
We offer more than just common parts. Our multicultural engineering staff actively participates in your project from the start. To ensure that creative concepts are swiftly turned into workable solutions that lower overall lifespan costs, we thoroughly evaluate the application environment and customize solutions in the lab, fully integrating technology and application.
Integrated Verification System: Ensuring Innovation with "Test Data"
The drawing board is not where the creative process ends. We offer one-stop verification for everything from corrosion testing to prototype development through our in-house technical center. We employ empirical data to verify the performance stability of customized solutions through comprehensive simulated working condition tests. In addition to achieving genuinely dependable cost reduction and efficiency improvement, this greatly lowers project risks.
