Can thread inside keensert after installation be verified gage?

Question:

KEENSERTS spec say "After installation of the kess into the parent material the assembly is form-closed. No check with a thread gauge according to DIN standard possible in the area of the kees."

Doe this mean the internal threads of the insert will no longer comply with the standard, or does this mean the threads of the parent material will no longer comply with the standard?

Answer:

The threads on the outside will off course not comply kncc0256j the threads on the inside should comply.

However since you specifiy a very thin and small insert, I can assume that due to a wrong installation potentially you could have damaged the inside threads on the section where the kees are.

This damage will be minor, but might be a small bent of the thread inwards.

I do not think this will be something very harmfull,  the only thing that it will bring is that the bolt that you screw into the installed keensert will be kind of locked by this ‘new’ locking feature that was created duet o wrong installation.

I do also think that the thicker and larger the insert this is not valid, and you can effectively put a go no go gage through it to check it.

Most tools have no threaded section to install the insert.

Therefore I would always recommend to install them with a threaded tool.

So far a threaded handtool has been developed only in Metric from size M4.

The smallest pneumatic or electrical tool in imperial that can be installed is cl1032j.
