Ruwag Nyloc Nut 20mm (5) is a set of five new nyloc nuts designed for secure fastening in automotive applications. This product is identified by SKU BB-406802 and typically used where a locking nut is required to resist loosening under vibration and torque. The 20mm size specifies its diameter, useful for matching with corresponding bolts or threaded components on your vehicle.
A nyloc nut includes a nylon insert that creates friction against the bolt thread, helping maintain a tight fit in dynamic conditions. These nuts are commonly found in chassis, suspension, or engine components where maintaining connection integrity is critical. When replacing worn or damaged nuts, comparing the size and type of your old nuts with this pack is essential to ensure compatibility.
This set of five nuts is ideal for buyers needing multiple units for repairs or maintenance tasks. Confirming the 20mm dimension against your vehicle’s requirements ensures you select the correct part. If uncertain about fitment or compatibility, consulting a specialist or using vehicle-specific search tools can help make an informed choice.
