This is a high - quality short cover screw for Briggs World Formula engines. It's an essential part for rocker cover installation, ensuring a tight and reliable fit.

To use this screw, first make sure the rocker cover and the engine surface are clean. Then, carefully align the screw with the holes in the rocker cover and start screwing it in by hand to avoid cross - threading. Once it's started, you can use a suitable screwdriver to tighten it properly. When tightening, don't over - tighten as it may damage the threads or the cover. As for maintenance, periodically check the screw for any signs of rust or looseness. If you notice rust, you can clean it with a wire brush and apply a light coat of anti - rust paint. Keep the screw in a dry place when not in use to prevent corrosion.
