I bought a bag of 1,000 Kold Kutter screws years ago to stud the ATV tires on my Polaris RZR. They are 1/2″ long. The track on the Snowdog could easily handle screws 3/4″ long but the ones I used work fine and I have not lost any. Pretty sure I used right around 120 screws and I staggered the pattern using three in one tread and 2 in the next. Really, the only condition the screws/studs are needed for is on glare ice or when there is just an inch or two of lose powder snow on top of bare ice. The dog has all of the weight right over the track so it does have a solid footprint and plows through rather than like a snowmobile that tends to float because of the skis. One time last year when going up a steep ramp I lost traction and had a buddy stand/kneel in the dogs rear for added weight and then it dug right in and walked right up.
