Dual-Material Options – 410 SS or Carbon Steel
Available in 410 stainless steel (HV 400-500, high torque for heavy metal penetration) or medium carbon steel (Grade 8.8-10.9). 410 grade penetrates light-gauge steel without tip breakage; carbon steel with black oxide coating offers durability and economy. Dual materials cover various project budgets and conditions.
Black Zinc/Black Oxide – Stealth Aesthetics
Finished with eco-friendly black zinc or black oxide, delivering a uniform matte black finish that resists moisture and salt spray. Strong adhesion with no chipping – color stays stable and rust-free. Seamlessly blends with black sheet metal, modern furniture, and automotive interiors.
Phillips Pan Head + Hardened Self-Drilling Tip
The Phillips pan head fits standard tools, delivering high torque without cam-out. The hardened self-drilling tip completes drilling, tapping, and fastening in one step – no pre-drilling needed. Anti-slip high-bite threads securely grip metal, wood, and plastic – resisting vibration and loosening.
