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