• Reliable installation and removal with a 2.5mm hex drive, preventing stripping and ensuring secure fastening in tight spaces
• Consistent thread engagement due to Class 6g thread fit and coarse pitch, providing vibration resistance and quick assembly
• Enhanced durability with Rockwell B55 hardness and 50,000 psi tensile strength, supporting long-term performance under stress
• Smooth, low-profile rounded button head minimizes snagging and offers a finished appearance for aesthetic-sensitive applications
• Full threading along the 16mm length ensures maximum grip and uniform load distribution across joined materials
• Compliance with RoHS 3 and REACH regulations guarantees environmental safety and meets global industry standards for procurement

Professional Applications & Engineering Value

This M4 brass rounded head screw is engineered to address common industrial challenges such as corrosion, vibration loosening, and assembly efficiency. The brass material naturally resists rust and galvanic corrosion, making it perfect for electrical enclosures, marine equipment, and plumbing systems where moisture exposure is frequent. Its hex drive design allows for high-torque application without cam-out, while the coarse metric thread (0.7mm pitch) ensures rapid installation in soft materials like plastics or wood, reducing labor time. The fully threaded M4 x 16mm configuration provides consistent clamping force, preventing joint failure in dynamic loads. Ideal for industrial fasteners in machinery, automotive, and consumer electronics, this screw combines mechanical strength with regulatory compliance for reliable, long-lasting assemblies.
