M3*4.5 Low Carbon Steel Torx Flat Head Machine Screw

Product Advantages

• Ultra-Low Profile Head: Engineered with a head thickness of just 0.55 mm, making it ideal for slim electronic enclosures where internal spatial tolerances are extremely tight.
• Precision Torx Anti-Cam-Out Drive: The internal Torx recess prevents driver slippage and stripped screw heads, allowing precise torque application during high-speed automated electronic assembly.
• Consumer Electronics Compatibility: Specially designed for micro-fastening applications in laptops, smartphones, keyboards, and handheld devices, delivering reliable structural stability without adding unnecessary weight.
• High-Precision Micro Threading: Features tightly controlled M3 threading with an exact 2.94 ± 0.04 mm diameter to guarantee smooth insertion and high resistance to thread stripping in delicate components.

Factory Advantages

• Micro-Fastener Customization: As a direct manufacturer, we specialize in high-precision micro screws, supporting custom micro-sizes, ultra-thin head profiles, and custom surface plating.
• Strict Quality Assurance: We employ rigorous dimensional inspection standards across raw material processing, cold forming, and thread rolling to ensure batch-to-batch consistency for electronics OEMs.
