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

The tuning key was the cheapest option on amazon (that actually worked) to tune my old Music Maker lap harp, that has 4 mm square pegs.I first bought a replacement tuning key on amazon that was like the one The Music Maker comes with. Those tuning keys look like a thin, flat piece of metal a few inches long, with a square hole at each end. I paid $7.50 for that one, but the metal was soft and warped, to the point of no longer working, by the second string I tried to tune. I was able to return it.This was the next cheapest option. It worked well & got my whole Music Maker lap harp tuned. Just the edges of the inner bore of the tuning key warped just slightly, but it was not enough to effect performance. The pictures are after use.This style tuning key is also a bit easier to make finer adjustments, since the handle is a longer lever than the tiny tuning keys the Music Maker comes with. Also the handle is out of the way of the other pegs when tuning, which is nice.The wood handle on this tuning key was smooth & seemed nice enough.If I was using a lap harp daily, & had money to spend, I might splurge for the $24 one I’ve seen on amazon, to see if the quality was even better, but this one works quite well for my needs.The bore of the tuning key fits 4 mm square pegs (and is just slightly larger than 4 mm square, in order to fit the pegs.) The length of the tuning key handle is about 4 inches.The pegs are 4 cm long, with 4 mm square ends. The threaded part of the pegs is about 5 mm diameter.I don’t know much about peg quality (I’m not using the ones this set came with, as I only needed the tuning key), but I’ve included pictures.

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?

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.

As described and works with my Music Maker lap harp that I was given about 10 years ago by a teenager so it's as least as old as that. It may be older so if you have an older version, it will likely work just fine. Simple to use, not sure why one would need the replacement tuning pins but it wasn't the reason I purchased it so it's a bonus for me.

Compliments Instrument.

I’m far from an expert, but these really brought my lyre to life. They were well labeled and hold tune better than the old ones. They’re definitely an upgrade. Recommended.

I am sure it works great for the right instrument but I purchased for my MusicMaker harp after reading the reviews. Unfortunately it did not work well- the key doesn’t fit low enough down on the pegs to turn the effectively and even did a bit of damage to the peg on which I attempted to use it. Returning was easy & satisfactory.
