Needed replacement cleats with smaller walls for aftermarket wheels. (OEM cleats did not work) This cleat set served its original purpose of providing a thinner wall for non-OE wheels. A wrench is required to assemble all grommets. Some additional security benefits are provided. The surface of the studs will scratch/splinter exposing the bare metal of the tips. The key is steel. The set arrived in a plastic bag. In addition, each eyelet is individually packed in its own bag. Good price. Acceptable quality.
