DIYers and professionals, this uxcell socket head cap screw pack is exactly what you need for those precision projects! You get 50 pieces of M2 x 25mm screws made from grade 12.9 alloy steel, which is seriously tough stuff. The black finish looks professional and provides some corrosion resistance, while the socket head design allows for flush mounting in tight spaces where regular bolt heads won't fit. With a thread diameter of 2mm, pitch of 0.4mm, and total length of 25mm, these are perfect for electronics, small machinery, 3D printer projects, or any application where you need strong, reliable fasteners in a compact size. The head diameter is 4mm with a height of 2mm, and they require a 1.5mm hex key for installation (not included, so make sure you have one handy). The 12.9 grade rating means these are high-strength bolts that can handle significant tension and shear forces for their size. Whether you're working on home appliances, communication equipment, machinery, or creative DIY projects, these socket head cap screws provide that perfect combination of strength, precision, and professional appearance. Having 50 pieces means you've got plenty for current projects and future repairs too. They're the kind of hardware that just works reliably without stripping or breaking, which is exactly what you want when you're building or repairing something important.
