M6 x 4mm?

[extrudedfeature]

I know this is a rather benign and add simple questions, I am looking for an M6x4mm done head alan bolt. I am struggling to find anything under 8mm.

If anyone knows of a company that produces bolts in these sizes it would be very useful.

Many Thanks

M6 x 4? Are you sure? Have you tried sketching that, the pitch angle extreme, I wouldn't call it a bolt any more, it's not able to hold anything.
I don't think you'll find it anywhere, probably has to be made from scratch.

Benta.

I agree with benta as far as holding power. We have used a few at M6 x 5 mm for tacking together some really thin sheet metal before a crimp and bend operation for a prototype enclosure. It was all the room we had. For production, they were replaced with rivets. Had to buy M6 x 8 and cut them.

Best to you,

Do you mean a standard M6 bolt with a 4mm length of thread from the shoulder?

As I expected really, the use of the bolt is more of a passive fixing, it bears very little weight. We have been cutting them down. It strikes me as odd that i can get a csk bolt who's threaded section is only 4mm, but not a dome head version, I think ill have to look into getting them made.


Thanks to you both!

Alan head? It is hard enough to make the bolt that small, much less punch a hex "hole" acccurately into the pressed-out "top" of the alan head screw accurately enough to insert a six sided (allen ?) wrench INTO that little bitty hole. If you can, use a regular external hex head and a metric nut driver.

Yes he is looking for a bolt M6 x 4mm long. Only in the US would this be read as M6 x 4mm pitch. I have never seen a Allen head bolt M6 x 4. I guess you may need to chuck an M6 x 8 and turn it down to 4mm length.
Just a question: how and where would you use a Soc. Hd. Cap Screw M6x4?

racookepe1978,

I would like to echo your opinion, but I do encounter M6 allen screws often, as well as snake-eyed spanner ones that size, inside security cameras. In one brand, I've even found a security-style hex with the pin sticking up in the middle. It was guarding the firmware. PAIN IN THE TAIL to work with.

There are a number of M4 screws in there, too, but the ones I've seen are all hex head, so not bad.


Best to you,
