This is a set of four screws for the neck pickup cover fitted to Gibson or Epiphone EB or SG basses. They are made from A2 stainless steel so they will retain their shine and never go rusty. The standard option are the same as size as original. The oversized screws are for repair purposes: They are shorter than original but have a bigger diameter thread and larger head. This is ideal if either the thread is stripped in the wood or, (as in my case, see photo), if the screws have been over tightened and pulled through the chrome cover. The larger head sits nicely and will not pull through.
