Priced as a single 1.75" Countersunk Bolt, and 3/8" Nut
Most set ups need 8 bolts and nuts in some form or fashion.
We would recommend 8. We have seen people not use 8. But we would use 8, call us over achievers.
The 1.75" size comes into play when you start adding risers or wedges/angled risers to your set ups. If you are using wedges/angle risers then you may only need as many bolts as you have taller sides.
