M4 × 0.7 × 16 mm screw is designed for assemblies requiring longer thread engagement while maintaining a low-profile, flush fit. Its flat, wide head ensures even pressure distribution and protects delicate surfaces. Made from AISI 304 stainless steel, it offers excellent corrosion resistance, making it suitable for industrial, marine, and outdoor environments. The B.O. (as-machined or brushed) finish provides a technical and professional look.
