Guitar Saddle Height Screw Guide

This article is an attempt to help guitarists find the correct bridge saddle height screws for their guitar. Due to Fender being…, well, very Fender-y, the rules below are not absolute. In their Fender’s own words, ‘On most’ is the great words of confidence we are left with to describe which screws fit which models. To get a bit closer to an absolute answer for you all, we have added the exact bridges that each screw fits.

The old adage, MIM and MIJ get metric M3’s, American Made get US #4-40’s is no longer correct as we now have some models getting a US fine thread #4-48.

This is a live document and will change as we get more information from our customers. Please bookmark for latest info we have.
