Need a securing screw fabricated

[Thru-hika]

Is there someone willing and able to produce a securing screw for me that will go to a rare Craftsman 1/4" socket holder. i have the pitch and the measurements and willing to pay or trade for your services. Let me know if someone here is available to fab this. Thank you!

Missing one of the three screws.

How about just buying a Knurled Low Head thumb Screw?

I concur, buy 3 and they match. If the radius on top matters a bunch to you then buy three high head screws and have the radius turned on the top again. The difficult part of that piece is finding the straight knurl of the correct pitch to duplicate the ones you have. It might be something common but odds are it is not.

Thanks for the insight guys. The tread diameter is 3/32 and the thread pitch is 36 so it looks like I'll need a 2-36. Head diameter is 3/8 as is the length of the threaded part of the screw. I can live with the esthetics not being perfect.

It seems 2-36 is uncommon as McMaster, Grainger and Fastenal don't seem to sell these -at least not online.

I'll keep looking. Thanks!

You sure it's not a 4-36? 7/64 should be the OD on a #4.

#2 is soo tiny. We have some #0 at work. Don't cough.

Looks like the dial caliper is reading .121/.122 maybe a #5? I'll get a 4-36 and 5-36, if there is such thing, and see which one fits best. This has been an enlightening exercise and thank you all for your help.

Are you reading the major diameter

.122 is a #5 screw

 

[larry_g]

Going out on a limb here but if that is old enough to predate SAE or unified standard screws then it very likely is a 1/8" , .125", screw with a 36 TPI. A lot of manufactures used their own standards in the 20s and 30s . I think I might be tempted to make a 8-36 threaded fit. An #8 screw is .164" dia.

How did you confirm the 36 TPI on the screw you have?

I used a thread pitch guage to see what the pitch was. As best as my eyes could tell it is a 36. If need be I can retread the holder to fit a larger screw if it comes to that. You guys are great. Thanks!

The OD of the threads is gonna be a good .005 (possibly more?) smaller than nominal.
