Silicon Bronze machine screws

Post by SteveM » Thu Jul 26, 2018 9:50 pm

I have about 30-40 pounds of silicon bronze machine screws left over from my dad's shop.

These are all new old stock in the original boxes. A few boxes have a light green corrosion on them, but most of them are like new, other than tarnish.

Sizes range from 6-32 to 1/4-20 in different lengths.

Prices vary, but if you show me what you are paying, I'll beat it.

If you want to buy in bulk, even better. I can ship the whole lot in a large flat-rate box, so shipping is cheap.

Are you making small-batch varieties for hobbyists?

I've been working down a collection and replenish it with scrap disassemblies. I do not have many in bronze though, and most newer stuff has junky fasteners.

What is the use for these, as opposed to steel or brass?

Bronze screws should not be confused with brass screws. They have far greater tensile strength, although I'm not able to quote the difference.

I recently rebuilt a couple of coils for induction furnaces. Someone, in the distant past, had replaced a couple of the silicon screws with brass screws, both of which had failed.

Right now, I don't have the time in my life to do the small batch thing.

The boxes are 100, and most are full.

These are very popular in marine applications. If you know someone with a boat yard, send them my way.
