Árbol guía de barra retenedora de cuerdas de latón Musiclily Pro de 45 mm para bajos eléctricos de 5 cuerdas

The string retainer works great

Like the other review, the screws are too short to be mounted on Fender-type necks. I luckily had longer chrome screws in my guitar hardware stash.

The mounting screws(15mm long) are way too short. For them to grab into my headstock I would create a break angle so sharp it would probably crack the nut. I contacted the seller to see if they could sent me a couple of ( 20mm) screws. They linked me to purchase a pack of 10 18mm long screws that seemed to be too fat. Also they cost 6 dollars. I usually like Musiclilly but not this time. These screws are long and skinny and they do not sell those at the local hardware store. Fortunately I never throw any screws away and I found a couple that work in my stash. That is the only reason why I gave two stars instead of just one.
