Zuorery 710-Piece M3 Screw Assortment Kit - 10.9 Grade Alloy Steel With Nuts & Washers

DIYers and makers, this Zuorery M3 screw kit is about to become your new best friend! With 710 pieces total, you'll have exactly the right fastener for pretty much any project. The kit includes eight different lengths - M3x6mm, 8mm, 10mm, 12mm, 16mm, 20mm, 25mm, and 30mm - plus matching nuts, flat washers, and a hex wrench. The 10.9 grade alloy steel is seriously tough stuff, designed for high-stress applications without becoming brittle. The black zinc plating provides excellent corrosion resistance while looking professional. What I really appreciate is the precision engineering - we're talking ±0.01mm tolerance on threads that are laser-cut for smooth engagement every time. The nuts fit snugly without wobbling, which saves so much frustration compared to cheap hardware store fasteners. The organized plastic case is a game-changer - each size has its own clearly labeled compartment, so you can find what you need in seconds instead of digging through a messy pile. They've even applied a light anti-rust oil to ensure everything stays in perfect condition. Perfect for 3D printing projects, RC models, furniture assembly, automotive repairs, electronics, and general workshop use. The hex socket head design gives you good torque transfer without stripping. Seriously, if you do any kind of building or repairing, having this comprehensive kit on hand will save you countless trips to the hardware store and so much time searching for the right size!
