Work perfectly
Put these on my rubber tracks , mini bull dozer , worked Great!!! No more sliding sideways backwards or forwards on steep driveways removing snow and ice. These are easy to install with the tool that comes with them, DO NOT pre-drill to install, just use the tool provided. I pre-drilled appx 20-30 studs in my under carriage. Lost every stud that I pre-drilled the under carriage for. Screw them in, set them fairly deep and they will stay put and give excellent traction on ice andsnow.

Work great
Super easy to install and really helps with grip in the winter. Way cheaper than having a shop do it.

Really TC? Seems suspicious
They barely make a mark on glass. Real Tungsten Carbide should scratch the hell out of everything except diamond.

Didn't last on my ATV
I spent several hours installing 400 of these on my Polaris side by side ATV. After plowing snow for one hour the majority of them had broken off even with the tread. They didn't come with any installation instructions but I drove them in as far as the included tool allowed.

Snow Bike is Now Ice Bike
Put these on my Fat Bike/Snow Bike because I dont want to be the source of a good chuckle when my bike slams me to the ice in front of 12 guys.They are awesome! Each bag came with a socket to drive them. I used my grinding wheel to shave off about 3/16 from the socket face. When you drive them with the socket, the Socket was digging into the tire. You either drive it part way with the socket, then tighten them in further with pliers, or grind the face off the socket.Studs themselves are perfect size (9 mm) and drive into the tire well.

Great Traction
The media could not be loaded. I make walking sticks, I use these carbide studs in the tip of the stick for hikers and people walking on ice.
