Hey guys. I'm trying to hide a retention screw in my blade holder (style 25), and an 8-32 is a little too big for where I'm trying to put it. Is a 4-40 screw too small to use as a retention screw?

Personal preference, I wouldn't use 4-40. Im no engineer so I don't even know where to begin to determine if it is indeed too small. I just wouldn't.
What kind of use is the saber intended for? Dueling, show? Will a 6-32 work?
Thanks for the reply! I don't duel aside from the occasional battle with my 4 year old. It will mostly be a show piece with a little light spinning.
I've used 6-32 before that have worked ok for light sword play. IDK, maybe others can chime in on the 4-40. It's just that the nose on those has such a small point of contact.
Yeah, and that is my biggest concern, with the screw being so narrow, I'm worried it would crack the blade.
Thanks for the input. I'll probably see if the 6-32 will work then. Thanks again for the help!
I used a 4-40 for the blade of a tiny hilt that won't be dueled with and it works okay. it's only got like a 12" 3/4" blade in it though. Its a Yoda type hilt.
4-40 retention screws can be used in other places, I like that you can fit one on MHS parts just in the threadless gap is between the edge of a male-thread side and the threads starting. Great way to lock aluminum disc chassis in and have the retention hidden when the saber is put together.
