Screw Type push retainers are used to hold 2 to 3 layers of plastic together at a mounting location. These Yamaha Style Fasteners are found all over the Yamaha Rhino and other machines. They are extremely handy due to the fact you only need to push them to install but are threaded and require a phillip head screwdriver to release them.
Fasteners are designed to fit a 1/4" hole and are sold in packs of 25.
