help with hammond box replacement screws? size, style etc?

[loss1234]

I have a bunch of hammond boxes in 1590 and up. I made the mistake of opening them up before I was ready to use them and over time, I lost all the screws!

Now that I have completed projects, I can't finish them as I can't shut them

So...does anyone know the Screw Size these boxes take?  I do have a hardware store near by but they always give me a hard time when I come in so if I had the correct
size to ask for it would help.

Or where I can get replacements?

I don't know much about hardware and have always been completely at a loss when I lose hardware as I don't know what to ask for at the store.


thanks!!!!

I believe the screw size is listed on the Hammond website and they are 6/32 screws.

If you call Hammond, they may send you some.... with a bit of begging of course

Be careful. 

What we think of as "Hammond boxes" can vary.  If what you have are ALL ordered from the exact same place, at the same time, then 6/32 may be what you need.  But I've spent several afternoons at a local place that has a 30-yd long wall of parts drawers full of fasteners, bolts, and screws in every size and form imaginable and stumped the customer service guy.  We mentally lump all those cast aluminum boxes as "Hammond" but there are many sources, some Chinese, and they vary with respect to whether they are metric or imperial, how deep the hole is (too long a screw and you can't tighten the bottom enough).

Yeh. I had a similar problem. I had boxes made by Hammond from various sources, plus 'round cornered' and 'square cornered' Eddystones. And I got the screws mixed up.

The screw sizes were all over the place. Most were 3mm x 12mm. Some were 3.5mm. One, only one, was 4mm and that was a square Eddystone (other identical boxes had 3.5mm holes).

Interestingly (kind of), none of them seemed to be 6/32 (which is close equivalent to 4mm).

EDIT: Perhaps I should have typed it like this: 6-32 screws

I have some replacement screws for "B" and "BB" size enclosures. But as others have noted, some makers use metric threads. This screw:

fits the New Sensor BB-size. I don't know if it fits Hammond.

This is why I have gotten all of my enclosures made and drilled for 6-32...

Shame on me. I had never heard of 6-32 screws. Forgive my ignorance.

I just opened up a couple of new Eddystone boxes, and inside was a little bag labelled M3 x 12.  So I checked with an M3 nut and, yep, they're M3 sure enough.

HOWEVER, they're a sloppy fit in the threaded holes in the enclosure. I found some non-metric screws (which I now know are 6-32) and they're a perfect fit. I wonder why the boxes don't come with the correct screws?
