gents,

what's the standard threading size for a safety razor handle? my wife's uncle owns a precision CNC shop and he might turn a handle for me if I can get him some dimensions and threading size.

thanks!

I am sure that others will chime in as well. It is my understanding that most razor handles and heads are 10-32 or M5x0.8. Since M5x0.8 is a little larger a handle threaded for it will work with the smaller 10-32. I know my custom handles m5x.8 worked with my New OC razor heads.

Go metric.

It will work with more razors.

You need to get the wife's uncle a few cases of beer. Butter him up and sweet talk him into making a bunch of stuff! We'll all chip in man!!!

Hahahaha.
Shave yourself.

By the way, I’ve seen a couple of cases lately where it’s been mentioned that the length of the threading on a head or in a handle is of irregular length. That might be something to also take into consideration, but I’m not sure if there is a standard. Probably best to make sure the threading in the handle is sufficiently long — better to have a little extra than to run out before the head is fastened.
Whenever I go to shave, I assume there’s someone else on the planet shaving, so I say “I’m gonna go shave, too.”

haha. he was very receptive to the idea, actually and was wanting me to get him the standard thread sizes so he can turn one. I'll be seeing him at the end of this month and will show him some of the handles on my current razors to get some ideas brewing.

The main exception that I know of is the Fatip, which I think has larger dimensions than the two stated above, so doesn't work really well with either of them.

The statement about the length is key though. Some razors won't like a longer threaded portion, so use a couple of your favorites to determine what length to use.

10-32 or M5x0.8

10-32 is old school, like vintage Gillette New etc. However, the Rockwell 6S also uses the SAE 10-32 threading because of manufacturing reasons. Just about everyone else uses the metric thread M5x0.8. If I was designing a head or handle, I would go metric. Exact compatibility is better than close enough compatibility. Compatibility with more razors is better than compatibility with fewer razors.

You can read about the pitch and diameter difference in this article.

thanks for the link. I'll be seeing my wife's uncle in about 2 weeks...I'll relay the information and show him some of my handles to see what he can come up with.
