  HLB

  SUNCO

  Uses both the top nut (convex type) and bottom nut (concave type).
  The top nut is perfectly circular with respect to the bolt, but the bottom nut has been eccentrically machined off-center with respect to the bolt.

  · Can be manually tightened to your desired position.
  · Can be used repeatedly.
  · HLB is for bearings.
