Hi!

I need screws to attach the handles to the tang of a knife but don´t want to thread the tang hole, so I need that kind that scrws to another screw - don´t know how it is called in English, but the construction is similar to cutlery rivets.
Does anyone knows where I can get them? Allen type, button head would be prefered.
Thanks in advance!

I think that what you are looking for is called a Corby rivet. the body of the Rivet is about 6MM in diameter and the shank is about 3MM. One side of the rivet has a male thread and the other has the corresponding female thread.

Just about all of the knifemaker's suppliers carry them in brass and stainless steel.

After installation the excess length is simply ground off and there is no indication that a threaded rivet has been used.

Ivan,
I have used what you are looking for. I obtained them from Texas Knifemaker's Supply. Their website is:

http://www.siteblazer.net/texasknife/

These are listed as Hidden Bolt Handle Fasteners. Their part number for brass is TKS-2-400B. For stainless, it is TKS-2-300B. I am looking at their 1997/98 catalog and they are priced at $1.25US.

Thank you three for the answers.
George, I´ve seen Corby bolts already but they are not what I am looking for, as I want the handles to disassemble. i should have left it clear in my first post, I think.
Darrel, I asked Les Halpern a while ago and he said he did not carry the scrws I need. By the way, the pictures of the last pieces you´ve been posting were stunning. Hope I can put my hands in one of your folders some day.
C L Wilkins, TKF does not show these itens in their site, but I´ll ask for a printed catalog.
Thanks again.

Ivan,
Most, if not all of the knifemaking suppy houses have incomplete catalogs on their websites. That is why I quoted the part numbers right out their catalog. As per your reply, these are NOT the bolts or screws that you are looking for but are the Corby rivets that George Tichbourne mentioned. Sorry about that, but check out this website:

This may be what you are looking for.

I have a few pivot pins fron folders made by a fellow in Michigan unfortunately I can't recall his name.

These pins are O1 bored and internally tapped and are supplied with 2 #2 allen head button head screws, one in each end.

Because the rod is threaded all of the way through the idea is to cut it off to the length that you need and the larger button head screws will hold the scales snugly against the folder's blade. I think that they are referred to simply as threaded pivot pins.

If the rod were locktighted into the tang the scales would be readily removable by removing the allen head screws.

That sounds like the "Luke rivets" in the Koval catalog. Or you could use Corby screws and cut a screwdriver slot after you trim to length.

Oops -- I just noticed the screws George is talking about are internally tapped. The ones in the Koval catalog are externally threaded.

Going with what George said, if he tang is thick enough, you could just tap holes in the tang and screw directly into them. You'd have to be careful to tap half way on each side, and get the screw lengths pretty accurate, but it should work.

Or slightly easier, offset the screws, so that there is only one screw in each hole. That way you don't have to worry about tapping the hole from both sides or getting the screw lengths as perfect.

Ivan, aren't those also called Chicago Screws? They are also used to attach handles to hand saws.
 
I just saw something called "allenuts" in the Reid Tool catalog (all sorts of fasteners, clamping equipment and tools), this might work for you. I haven't seen them on their web page but you can request a catalog and get the phone numbers at www.reidtool.com

Thank you all for your answers.
I decided to thread the steel tang, as I can do this with screws availabile here in Brazil.
Best regards
