Help scope base 6-48 thread bolt

[armenjs802]

Clean the hole up with a properly ground bottoming tap and replace screw. Trim new screw to proper length. If the hole is trashed (it doesn't look it from the picture) run it oversize to .146-48 and fit an oversize screw.
Clean, lightly oiled threads in this application do not need locking goo.

Thanks! good point brother. It might have been the barrel thread down there that buggered up the end of that original screw.
Looks like it was tapped before the barrel was installed, and those look like the barrel threads at the bottom of the hole. Provided I have a few good threads at the top (seems like I do), then I think just need to shorten the screw by file.
Busy with camera!!

OP

A quick thank you for posting up all the pics and what happened... I learn something new all the time from threads like this.....

Randall- I was wondering why the tip of the screw was smaller. Your explanation makes sense

Thanks for your interest! this may go to OT for me at least and I be happy to bring you guys with me. Hope it helps the next man. More updates by weekend, I am working today. A long class for all of us!

Both products are clearly labeled on packaging for the intended diameters they are engineered for.

Because you are comparing specific part numbers, not colors.
There are a bunch of different part numbers within each color.
Different viscosities for different fastener sizes.

I was not comparing any "part #s" The quotes came from the Henkel-LocTite link. And they are color coded.

First quote labeled PURPLE. Second quote labeled BLUE.

Click the link, quotes were from pg 8, full product line application is on pg10.

The ONLY low strength BLUE recommended for fasteners UNDER 1/4". Is the "WICKING GRADE".

After seeing your latest clear closeup pics of the hole. I agree with "old-dog4570". Bottom tap and a proper length screw and you are gonna be fine. With the caveat, that I'm more anal retentive and would use Purple Goo. Even after 25 yrs of not using it, problem free. I've had it for the last 25 yrs, so I use it.

Then again, I even epoxy my bases to the receiver.

Love it. I ordered the tap, and today the scope is arriving. I may just do trial to see how the scope clearance looks like?
