The PQ-5042-00 is a great option to upgrade the nut on your Fender style electric guitar (or a guitar with similar specs).  It is pre-slotted for a quick and simple install.  It is 3/16″ tall so make sure that is enough height for your guitar.

The PQ-5042-00 is also available in a convenient 10 pack (LQ-5042-00).
