Here at ZRP we were tired of stripping out the helix bolts on the Arctic Cat Team secondary clutches and having to pay more than $5.50 each to replace them.
We knew there was a better way so we sourced our own solution. Our bolts use a larger drive (T-30 vs T-27) which helps prevent stripping and our bolts also feature a Torx-Plus drive design which maximizes bit surface area to prevent stripping and can be used with the traditional Torx bits you already have or you can upgrade to a Torx-Plus bit for even better grip.
The best part: Our bolt are only $8 for a set of 4 vs $23 if you buy them from Cat.
In summary: You get a much better bolt for only 1/3 the price.
