Higher density materials such as tungsten, reduce vibration and reverse while riveting and reduce the risk of injury, tension and wrist fatigue. Take notes from professionals and use what they use. Our wide range of shapes and sizes allow you to properly rivet even in tight or hard to reach areas. Over fifty years of experience culminated in these premium quality dive bars, and you can benefit from that experience.
