6-32 Insert Screws
6-32 Insert Screws
I bought a set of 5 insert type lathe cutting tools from Enco last year and the screws have turned out to be soft as butter.
I measured them and they appear to be 6-32 insert type screws. Not the straight sided heads but the ones with the taperd heads that fit in the TNMG inserts.
Does anyone know where I can buy these screws? I have checked McMasters Carr and Enco and if they have them they list them in a way that I can't really tell what I am looking at as far as size and head configuration.
I also ran a 6-32 tap into the hole and it goes in by hand so it they must be 6-32 screws!

DaveC , went to McMaster-Carr website and did a little digging . The bevel head screws have a 82 degree angle on them . Page # 3090 ,http://www.mcmaster.com/#about-flat-hea ... ws/=2zh3fu
6-32
Coal Miner,
Hum, I never thought of using simple SHCS. I'll double check the seating angle on the Inserts and see if this will work. If it does then the price is certainly much better than the $2.50 a screw that I have seen.
I'm looking at part #91253A150 @ 100 pieces for $10.87
Thanks,
Dave C.

Are these the tools you are using?
Anyone that sells these toolholders also sells replacement screws. MSC is also a good source to find screws for holding carbide inserts in place.
I also use the toolholders shown in the pic. I usually have replacement screws on hand. But, in a pinch I have used socket head flat head screws. I file a taper on the top of the screw head so the chips flow over the screw head.
Avoid over thightening the screws. Just Snug them up. They seem to tighten themselves.

One of the most awsome pictures in my memory is that of a tiny screw, now that I think of it, it likey was to be an insert holding screw, in a giant 12x36" lathe 3 jaw chuck, with the head getting a bevel on it with the compound to cut the taper
(may need to make a collet to do it yourself to hold such a small screw, or custom jaws.... kinda think you might wanna work a tiny bit futher from the chuck myself)

Tools
Jim,
Yes, those look like the set I bought from Enco. I checked the catalog and I don't see any replacement screws. Not sure I would want them anyway as the ones I got were very soft and yes, they did self tighten. The socket heads just strip when you try to remove them. I took a hacksaw and made slots in the heads to remove them with a screwdriver. I got them out but I need something to replace them with that is going to last.
Thanks,
Dave C.

Right here in a box called replacement hold down screws:I checked the catalog and I don't see any replacement screws.

You probably need pt #422-3696 or #422-3692
If you like MSC:

Someday you should upgrade to this toolholder. Uses the same insert.
Insert clamping system is much better. Bought mine on sale for $39.90.

Correction
Jim,
Yes, I have to correct myself. I did see those screws from Enco but they did not state a thread pitch so I wasn't sure if they would fit or not? Strange, import tool holder using a 6-32 thread, maybe not.
The screws shown were for the USA brand and mine are not USA. I wish they were!
Anyway, at $2.18 A SCREW I thought I would look elsewhere. A bag 0f 50 screws from MCMaster Carr was only $5.00 so I'll see howthey work.
I looked at those other tool holders. Very nice!

6-32 Screws
Black_Moons,
McMasters-Carr does not say what grade the screws are. Anything has to be harder than the soft as butter ones that came with the lathe tools.
I have used some of these 82 Degree flat head screws for other stuff and they are pretty hard.
I should have them in this week and I'll post a pic or something to show if they work.
