Grip Studs® traction studs perform like no other screw–in tire studs on the market. Unlike typical sheet-metal-style studs, Grip Studs® have a patented wide-auger, self-tapping thread design that makes them easy to install without the need for pre-drilling, and gives them unparalleled holding power in rubber. Their tempered-steel-encased carbide construction added to their easy installation and removal are features only to be found in a product designed for optimum quality and performance. Varying depths and lengths ensure non-stop traction from tires or boots on ice, snow, frozen pavement, mud, slimy rocks, or ocean vegetation. Grip Studs® – unquestionably in a class of their own!
