    Work great and look good

    I bought these junction box cover nuts for my 1992 OBS Chevy. They look great and for the price you can’t beat them.

    Nice Nuts

    made of metal , not cheap plastic. Smaller than the stock plastic ones . You can use a socket to tighten them. I suggest using a flat washer before installing. Over all a great price and well made.

    Junction box cover nut

    These nuts are far superior than the plastic oem ones. They’re very sturdy and stay tight. Great price and product.
