I used these:

After my tapped 1/4-20 bolts pulled through the tapped boom on my boat.
I drilled out the hole, put these in, tightened them up and
re-installed the bolts. So far so good.

Hi Bill,
I would lean towards SS rivets as suggested by Dennis and others.
You will need to get the
diameter of the hole but also the combined thickness of the fitting
and mast. Fogh has a good
assortment of the rivets. You can get the compound riveter from
Princess Auto.
On the LO300 with all the reaching not having a vang was likely a
significant problem. Did
you rig a temporary block or anything?
