If the grip range is too low (or the thickness of the wall too big), the
threaded hole will be deformed. This will make it impossible to screw the bolt.
If you have problems driving the bolt in, drill the RivNut out and use one with
a bigger grip range.
I found that the RivNuts that come by def

Once again, I appreciate your insight. Today I ordered some
RivNuts and a tool. I was concerned about the tight tolerance of the grip
range, so I did additional research. I found aluminum RivNuts with a
broader grip range, so I decided to order them. In addition, it o

Nope. Collar floats with cabin roof. Mast has holes below the collar for
some sort of restraint but are not used.
The upward load is borne entirely by the mast since the turning blocks are
bolted to the mast. There is nothing attached to the collar at all.

Be very careful about the grip range. The RivNuts come in different sizes
(guess how I know). Measure the thickness of the boom wall and get the right
RivNuts.
When I needed them, I had to switch between imperial and metric to find the
right size.
Good luck

Dennis,
Isn't your collar restrained by collar brackets on either side of the

brackets transfer the load to the mast and not to cabin top.

I have something similar now, but possibly my blocks are too small. They are
from Garhauer but only have two screws in each one. The backing plates are
bending and I've replaced several of the screws with rivets.
I don't see your blocks or mine in their catalog so I'm probably looking in the
Bob,
The plate should be a collar. Not sure what you're trying to do, but if
you're adding halyard turning blocks, I strongly suggest you consider
attaching the turning blocks to the mast like this:

A hand rivet tool is cheap and if you ask around I’ll bet someone will have
one. That said, did you try an “ez-out”. Also not expensive and works great
if the bolts aren’t “frozen”

Also, in response to Marek: the pulling load appears to be handled by the
track. The bolts prevent the boom vang fitting from moving back and forth.
Also, I plan to use the same length bolts, if possible. If I need to go
slightly longer for the RivNut, so be it. Thanks.

Getting ready to pull the trigger on the RivNut idea. The stainless RivNuts
I found have a grip range of 0.027"-0.125". I was able to measure the
thickness of the aluminum I'm going through: 1/8" (maybe a micron or two
heavy), which is the top of the range. For those familiar with these
things,
>From what I know, the RivNuts are better for shear load (rather than for pull).
Also, be careful how long the bolts you use. You don't want the bolts sticking
inside the boom (if you have any lines going there).
Just a few cents

Hi Matt,
Did you consider riveting it in? They will often fit in screw holes that were
pulled out, are easy to install, and are quite strong. If you get to a larger
rivet size a cheap hydraulic puller from Harbor Freight will get the job done
nicely.

You can take the forward nut off the keel bolt, or any ONE nut for that

I would also put a hose around the bolt or similar to keep from epoxying the
