Threaded Fastner

[mwatp14]

Hi, glad to be making first post.

I have a lock nut that is used to retain some components inside a cylindrical part. It has an internal hex, for installation, and is threaded externally (i.e. the cylindrical part is the femal thread, lock nut is male). I think I may have misunderstood the type of fastner it is and I cannot find any specification for this type of fastener and its associated thread.

Can anyone help identify where I may find this?

Thanks,

MWATP

Extrenally threaded it would be a screw. Internal hex screw. Grub screw. Set screw.

I have seen this type of part before; it is sort of like a hex socket pipe plug, but it has a machine screw thread so it can free-spin down into a tapped hole. I am not aware of a standard for these parts; they are pretty unusual.

Its basic configuration does match a set screw or grub screw (as called in the UK) but other factors may influence its designation. What kind of size (both thread and 'length') are we talking.

Sounds like it may be a "hex drive plug" or some such.

It sounds like an allen head setscrew ( Grubscrew)

Does it look like one of these?

Post a photograph of your screw - then, determine what you want to do with the info: Buy more? Build more? replace it with an equal?

I agree that it is an allen head set screw.
