Home made screws
« on: April 01, 2021, 04:13:25 PM »
I got a few samples of M1.2 screws for a project and wasn't happy with the quality or material so I decided to make my own. I would have to turn down the head and shorten commercial screws anyway.

It went a lot quicker than I thought. Once I had worked out a "mass production" method I made around 40 ( I need 80+) before running out of silver steel. That took about 6 hours workshop (kitchen table) time.

Here is one on a penny.



This is unfinished - it still needs chamfering, polishing and blueing.

I'm quite happy with the result.

Very nice!  And tiny. How did you cut the threads, single point on lathe, die?

Great work! If you can make your own hardware you can build anything. What did you use to cut the slots? I've used a jewelers hand saw in the past but I'd like more consistent results.

I made the ones shown below to restore a clock several years ago.

Nice.  I bought a bunch of hex stock awhile back, and plan to use it making hex bolts and nuts for various projects.

Being able to make my own bolts, nuts, washers, etc. is, I'm not sure how to express it, 'the ultimate?', 'symbolic?'. Certainly satisfying.
It's part of "I have a shop! I can fix things! I can create things! I can put things together! Perhaps more than making any other part.

And I don't have to wait for an order or go to the store and buy a dozen when I need one.

P.S. I use a slitting saw to cut the groove. At least, so far.

Nice job Steve. Good post.

Nice work!

When you've got some turret lathe stuff it creates a strong compulsion to make fasteners.  :).  They take forever to set up, including making lots of tooling, but when they are ready, man can they crank it out!

I make my own fasteners, sometimes, if its not available, a long wait or I feeling particularly cheap (all too often!).  The formulae for a good model engineer might be a decent machinist with a dogged determination to survive tedium.  Spent all last weekend making little valve parts, 30 sets.  Extremely tedious but I'm still here so I must be getting better at model engineering :)

I bought a Russian made M1.2 thread roller on ebay for 13.01 inc. postage from St. Petersberg. Fantastic value for money.

Nice work Steve. Very satisfying when you can make your own screws and nuts, especially at such small scale.
