Both rivet body and mandrel are made of high quality aluminum alloy, suitable for a variety of applications. The expandable design of the rivet forms three legs, making it ideal for holding soft or thin workpieces and preventing deformation of the workpiece. The split tail structure provides a larger bearing surface on the back, distributing the load evenly and improving rivet performance. The mandrel is securely attached, which prevents damage, electrical failure or noise problems caused by a loose chuck. Designed specifically for plastic parts, it provides a secure holding effect without damaging the material., Manufacturer: LWYLY
