M3 × 0.5 × 30 mm screw is designed for applications requiring extended thread length while ensuring a flush and discreet mount. Its flat, wide, and thin head provides excellent clamping force distribution. Made of AISI 304 stainless steel, it offers high corrosion resistance, making it ideal for industrial, electronic, or mechanical environments. The B.O. (as-machined or brushed) finish gives it a clean, technical appearance.
