DIYers and RC enthusiasts, this BRINGSMART flange coupling set is exactly what you need for connecting motors and shafts! The 8mm inner diameter works perfectly with standard motors and the plating steel construction is seriously durable. Each coupling has an inner diameter of 0.31\, cylinder outer diameter of 0.63\, and base diameter of 1.26\ - nice compact size that doesn't take up much space. The package includes 2 couplings, 8 M4 screws, and a wrench so you have everything you need for installation. The heat and electroplated process makes these things resistant to oil and rust, so they'll hold up well over time. The hardness is better than copper or aluminum alloy, so you get reliable performance without worrying about wear. Perfect for RC models, 3D printers, CNC machines, or any project where you need to connect two shafts securely. The compact structure ensures proper alignment between shafts, which is crucial for smooth operation. Installation is straightforward - just slide them onto your shafts, tighten the screws with the included wrench, and you're good to go. Much better quality than you'd expect for the price and they work exactly as advertised!
