I wonder if it’s something similar to this quote from a Hinterhoeller bulletin titled “Maintenance of Spars” that I found on the Nonsuch.org website under Maintenance - Spars and Rigging Technical Info:
When stepping the spar each season, be sure that the four retaining bolts at
the sides of the mast step are backed out so as not to prevent the spar from
seating properly in the step. Apply “Locktite” to these bolts and tighten them
against the spar heel to eliminate any movement of the mast within the step.
