Woody's Gold Digger Modified studs feature a sharpened 45° carbide tip and a patented Traction Master head that cups the track for rigidity and support. Designed for two-ply tracks and support plates, they are through-hardened carbon steel with a 1-inch head and include the proper nuts. The 1.325-inch length is intended for use with support plates, and Woody's recommends studs protrude 1/4 to 3/8 inch over the track lug.
