These galvanized plus hard cross recessed pan (round) head machine screws, available in M1.7, M2, M3, and M4 sizes, are engineered for precision fastening in small-scale, high-demand applications. Crafted with galvanized plus hardening treatment, they offer superior corrosion resistance, enhanced hardness, and long-lasting durability, making them suitable for both indoor and mild outdoor use. The cross groove (cross recessed) design ensures easy installation with standard Phillips screwdrivers, while the pan (round) head provides a low-profile, smooth finish that sits flush with fastened surfaces, ideal for precision equipment and mini hardware projects.

 

Featuring precise machine teeth, these small screws deliver tight, secure connections that resist loosening, even in vibration-prone environments. The galvanized coating not only protects against rust and wear but also enhances the screw’s overall strength, making it perfect for lightweight yet critical applications. Widely used in electronic device assembly (such as circuit boards, small appliances), precision equipment maintenance, mini DIY projects, toy assembly, and small hardware installations, these screws meet the strict requirements of delicate and compact fastening tasks.

 

Designed for versatility, they are compatible with a variety of materials, including plastic, wood, thin metal, and electronic components. Whether for professional electronics manufacturing, small workshops, or DIY enthusiasts, these M1.7-M4 galvanized plus hard cross pan head machine screws provide a reliable, easy-to-use fastening solution for all small-scale precision needs.
