Corby Rivets vs Hidden Bolt Fasteners

How are Corby Rivets used to hold scales? They seem to have a slotted side for a screwdriver. Do you grind the slot down so both sides are smooth?

Are Corby Rivets and Hidden Bolt Fasteners the same things, but different names?

I would like to try using these on a knife project and would like to learn about them first.

Slots are typically ground off after they're epoxied and tightened on, Steve.

As far as I know they are the same thing. I may be wrong.

Be sure and buy the appropriate step drill if you get the bolts. I prefer piloted countersinks, but they are subtantially more expensive.

Hi Mike:

Merry Christmas.

I assume you have to countersink (recess) a hole in the scale for the corby rivet head. I saw the bit on knifekits.com. How do you know how deep to recess the heads? Trial and error until you think you have enough threads engaged and then grind the heads flat?

I measure them against the scale pair before I started, Steve. I liked to leave 1/16-1/8" of scale "below" the bolt. You can buy plastic "depth stop markers" that clamp on the bit, get real fancy using dial indicators or setting depth stops on drillpresses, or use the cheapo version by wrapping several winds of masking tape around the bit. 3-5 winds of carefully placed tape and exercising good attention will work just as well as the fancy stuff.

i frequently ground part of the threads and part of the "nut" off to make sure I didn't have just a wee bit of the thick part into the handle.

Merry Christmas to you too! Best wishes for a Happy 2006!

Hello Cavetech;
The hidden bolt fasteners are made different than the Corby bolts.
Each of the heads of the hidden bolt fasteners have a tapped hole going part of the way through the head and it has a short piece of all thread that connects the to heads together.
The Corby bolt have a male and female threaded ends. I like the Corby bolts better than the hidden bolt fasteners, they seem to be easier to use.
