This 3rd generation bolt assembly includes a custom bolt, lock washer, rack, and e-clip that allows the Heel Bracket to be adjusted to your boot size. This bolt should be very firmly hand tight to reduce chance of loosening during skiing (10 N-m or 7.4 ft-lbs). Works with BMF/R and BMF/3. The e-clip is not required for proper function, but keeps the bolt from fully un-threading when adjusting the binding to different boot sizes.
Sold as each.
