Do you have a liquid or fan cooled sled? How good of condition is the track in?
Deteriorated rubber will not hold them well and you are likely to throw them like shrapnel into your heat exchangers. Standard studs are not that pricey and 100% worth the investment IMO. Especially for a sled used on the ice.
A fan cooled sled that has practically new rubber and is not used on the trails at all.... I would maybe consider the screws.
