harken torque screws

[Bobg]

Does anyone know what size torque screws are on a Harken 1-188 roller furler, went to pull in the head sail and all that happened is the furler line came out, upon further inspection, I noticed the 2 torque screws were gone.  Should  be put on a pm list.  Had to lower the headsail in some pretty good winds.  most of the time they are covered with the furling line.
I think it is 1/4-28.  But unable to find any in the local marine stores.  Thank you  Bob

Bob : Personally I'd call Harken @ (414)691-3320 and get it from the "Horses Mouth" !!
