Snap-on’s new Metric/SAE Magnetic Socket Holders contain 30 percent stronger magnets than the previous model, come in four popular colors (red, black, green and orange) and are offered in three different drive sizes (1/4, 3/8 and 1/2 inch drive). The holder is designed to fit standard chrome and impact sockets. Rubber over-molding keeps sockets in place, and techs can promptly locate the right size with easy-to-read size indicators.
