These Kold Kutter Canadian Outlaw screws are serious business for ice racing and winter traction! They're #12-11 x 1.00 inch screws that come in a 500-pack - perfect if you need to outfit multiple tires or have plenty of spares. The increased Rockwell hardness means they're tough enough to bite into ice without bending or breaking easily. The Outlaw version has a taller head height of .290 inches compared to the AMA Race screws, which gives you more material to work with. The strong head edge design prevents stripping when you're driving them into tires. These are specifically designed for getting maximum grip on icy surfaces - whether you're racing, riding in winter conditions, or just need extra traction. The #12 size is nice and substantial without being overly bulky. Perfect for snowmobile tracks, ice racing tires, or any situation where you need reliable traction on slippery surfaces. The quality is exactly what you'd expect from Kold Kutter - they know their stuff when it comes to winter traction products. Much more effective than studs for certain applications, and way easier to install than you might think. If you're serious about winter sports or need reliable traction in icy conditions, these screws deliver professional-grade performance.
