## Before you buy

- Compatibility is described broadly for Floyd Rose-style, Strat and Squier guitars. Confirm the instrument's nut width, string spacing and top-mount screw layout before ordering. The listing uses both “metal” and “Zinc alloy” for material, so the exact material description is inconsistent.

## A good fit for

- Guitar owners replacing a locking nut who can confirm a 42 mm fit and matching top-mount layout.
- Players maintaining a Floyd Rose-style double-lock system or a compatible Strat or Squier-style guitar.

## Less suited to

- Buyers whose guitar requires a different nut width, string spacing or mounting arrangement.

## Customer feedback

The listing shows only a small set of ratings, all in the five-star category. That is a limited positive signal, not enough to establish how the nut fits particular guitars or performs over time. Buyers should rely on the listed dimensions and confirm compatibility with their instrument.
