### ⭐⭐⭐⭐ Nut or Bolt Head Covers.
*by C***T on October 1, 2025*

These are acorn shaped cosmetic bolt or nut caps. They fit and hold (for the month I’ve had them on). They look good. No real complaints, but the material is not the same quality as OEM, hence the one star off. But, if that is not an issue for the end user, then 5 stars. I’m more than a little OCD when my vehicles are involved.
