Calling all DIYers and model builders! This pack of 20 stainless steel rods is perfect for all kinds of projects. Each rod is made from high-quality 304 stainless steel—super strong, rust-resistant, and corrosion-proof. They measure 0.5mm in diameter and 400mm long (about 0.02 inches by 15.75 inches), so they're slim yet sturdy. Use them as shafts for model cars, helicopters, airplanes, gears, motors, or even small structural supports in craft projects. The surface is smooth and easy to cut or shape with basic tools, so you can customize them to any length you need. Whether you're fixing a toy, building a mini machine, or just experimenting, these rods are reliable and versatile. The silver finish looks clean and professional. Just keep in mind there might be a slight 1-5mm measurement variance due to manual cutting. Get creative and build something awesome with these handy rods!
