I just did this method to hide a locking screw on a part that I am building for a member here. I didn't want any movement so I drilled a hole and tapped it. Countersunk the top of the hole. Took a screw and annealed it, screwed it in, and smashed it down. I filed and sanded and WOW! you cant even tell where the screw that I put in is.

FTW great tip Eric, thanks for sharing

Great tip. Thanks!

I did something similar except with a set screw that was intentionally too long for the hole. Threaded in with high temp threadlocker, ground off the head and blued the exposed shaft.

 

Same as your technique except you don't have to countersink the head, possibly a little less work.

Great trick, thanks for sharing!
