Liyafy 30Pcs 40mm Tuning Pin Nails with Brass Rivets Set for Lyre Harp Small Harp Musical Stringed Instrument

I bought a couple boxes of these to use for a craft project. We made zithers. So, in case you're curious, the string holes are big enough for thin twine. I stuck a couple at the end of a furring strip, attached an empty peanut butter jar for a resonating chamber, and strung it up with twine. The kids had fun making and playing a simple zither. I'm sure they work great for their intended purpose as well, i.e. as autoharp tuning pegs. But why not experiment a bit, yeah?

Seems good, measurements off. I'm using this for something that requires accuracy and I'll have to make changes to fit these otherwise decent tuning pins

These are a great value if you're building a harp. The threads are just the right size, not too fine. This deal also comes with harp eyelets, but you will need to provide your own tuning wrench.

I bought this 30 piece (actually 60 with the hole guards) set for a zither project I was making. It was great to be able to utilize the entire set on one instrument except it never worked out that way. First off, there were zero instructions. It would’ve been nice to know the correct hole diameters for the pins and the guides. I had to use a hole gauge and guess. Second, the string holes weren’t large enough to accommodate the bass strings of the project, which actually were just the low E strings on a guitar. Finally, given the tension and all, I snapped off three of them right at the string hole while trying to tune them. These things are made of very cheap metal and cannot take much strain, reminding me of plastic instead of metal. It would’ve been nice if they’d used tempered steel, though I don’t know how radical that would’ve upped the price. So far, I now have a partial string setup but will not bother replacing them because I swapped the bass string ones for the others I broke. Since the holes aren’t large enough anyway, I either need a heavier pin, or will just leave them off. This product sort of works but I wouldn’t recommend them for anything complex unless you can get the exact recommended drill sizes. Maybe it would work for a 5 string Kantele where you can afford to break a lot of them first. Even then, given the quality of the metal, I wouldn’t hold my breath. Can’t recommend them.

Tiny little something, essential to build a lyre. Great quality!

Some threads don’t work (about 2-3 out of 40)

These pins are made of a cheap type of steel and do not allow a tuning tool to be used for screwing the pins. The square pin pegs easily scrapes off with any pressure but the worse thing is that they taper from a small square down to a larger square where the strings are inserted. Once the strings are inserted the tool will not work because it can't reach where the tool can bite the pin. Worthless, don't buy.
