M5*20 Low Carbon Steel Torx Large Pan Head Screw

Product Advantages

• Large Pan Head Surface Area: The oversized 15 mm head diameter distributes clamping force over a broader area, preventing material crushing or cracking on soft plastic automotive interior trim.
• Anti-Slippage Torx Drive: The precision internal Torx recess ensures maximum torque transfer without bit slippage, reducing wear on assembly tool bits during continuous high-speed production line installation.
• Black Zinc-Nickel Alloy Coating: Features an advanced black zinc-nickel surface plating that combines superior waterproof and rust-proofing capabilities with a clean, low-reflection aesthetic for modern vehicle interiors.
• High-Precision Threading: Manufactured with strict M5 thread tolerances (4.9 ± 0.03 mm) to ensure smooth drive insertion and exceptional pull-out resistance under operational vibration.

Factory Advantages

• OEM Tailored Manufacturing: We offer full custom production based on technical blueprints, adjusting head dimensions, thread pitch, overall length, and protective surface treatments.
• End-to-End Quality Management: Operating as a direct production facility, we maintain strict quality control protocols across raw material selection, thread forming, and surface coating processes to guarantee long-term reliability for B2B global clients.
