pinging
Explanation:
Or ping-test (not to be confused with IP pinging).
Probably as unusual as 'spechten'. The honor goes to Jack for knowing what it is. I was just curious if there was an alternative for 'acoustic tapping' that comes closer to 'spechten', which led me to 'pinging'.

"Experience helps. I recall reading a story of a shop that builds big aparatus and the shop personnel would tighten large fasteners by hand then check the "tightness" by striking the fastener with a steel hammer and listening to the pitch of the resulting ping. Too low a pitch, not tight enough. Too high a pitch, too tight. When the suits (design engineers) came to visit out came the torque wrenches. One day a suit showed up unexpectedly and saw how things were being done. He used a torque wrench to test all the fasteners that had been done with the ping test and found them all to be well within tolerance, most within only a couple of ft-lbs."

Once the collar is swaged on, no additional tightening with a torque wrench is required. A simple sound test by pinging it with a hammer verifies the tightness of fit.

acoustic tapping


Explanation:
Given your further context I think my suggestion in the discussion section (see above) is probably correct, Carmen. For that reason, I'm entering it as a formal answer. Please feel free to award of not award points for it and to close the question. In any case, according to KudoZ you should indeed wait 24 hours before doing that. Who knows, someone might come up with a better solution!

pecking


Explanation:
It may sound odd, given the additional meaning of kissing, but a 'woodpecker' (the bird) is a 'specht' in Dutch, so 'pecking' might fit the bill. 'To peck' does mean 'to strike with a pointed instrument', too.
