Spreader base corrosion

[svtatoosh]

Hi Folks,

Re-rigging an Alajuela 38. On trying to pull the spreader bases, with four 1/4 screws tapped in the mast (I assume): 2 of the nuts spin off ok with the threaded screw not turning at all; the other two nuts galled to screw but the screw turns and just spins and doesn't come out. Was wondering how were these probably installed originally? I had planed on re-tapping for new & larger fasteners. No access for threading a nut on from the inside of the mast. Should I just remove the fasteners best way I can? Please see jpg.

Thanks!

Use Duralac or Tef-Gel on the new screws to prevent electrolytic corrosion.
