M3 × 15mm Nut Bolts and Washers (5 PCS)

The M3 × 15mm Nut Bolts and Washers (5 PCS) set is a high-quality fastening solution designed for secure and reliable assembly in electronics, robotics, mechanical projects, and DIY applications. Each set includes M3 × 15mm machine bolts, matching hex nuts, and flat washers, providing everything needed to create strong, stable, and vibration-resistant connections.

Manufactured from high-quality metal with a corrosion-resistant finish, these fasteners offer excellent mechanical strength, durability, and long service life. They are designed to withstand regular assembly and disassembly without compromising thread quality, making them ideal for both permanent installations and prototype development.

The included flat washers help distribute the clamping force evenly across the mounting surface, reducing the risk of material damage, preventing loosening due to vibration, and improving the overall stability of the assembly. The M3 thread size is one of the most commonly used standards in electronics and mechanical engineering, making these fasteners compatible with a wide variety of components and accessories.

The M3 × 15mm Nut Bolts and Washers are widely used for PCB mounting, Arduino and Raspberry Pi projects, robotics, motor brackets, sensor mounting, electronic enclosures, 3D printer assemblies, drone frames, automation equipment, mechanical prototypes, and educational engineering projects. Their compact size and reliable fastening capability make them suitable for both hobbyists and professional engineers.

Supplied as a pack of 5 complete sets, this kit provides a convenient and cost-effective solution for repairs, maintenance, prototyping, and new project assembly.
