The 10×30 mm Coller Nut Bolt (50 Pcs Pack) is a reliable fastening solution designed for electric vehicles, electric scooters, and automotive structural assemblies. Each bolt features an integrated collar (flange) that helps distribute load evenly, improving joint stability and reducing surface damage without requiring an additional washer.
Made from high-strength hardened steel, these bolts are built to withstand vibration, mechanical stress, and daily operational wear. Precision threading ensures smooth installation and a firm, secure fit, making them suitable for both OEM manufacturing and repair workshops.
