Well, it went into the hole , I turned it clockwise and viola! The two parts held together! It must be aviation wizardry! Parts were consistent in manufacture and high quality.
This was exactly what I needed and am appreciative of the availability from Spruce.
Received exactly what I ordered.
Arrived as expected, MS51957-48 quality was as expected, performed as expected in the application. Thank you for asking
These screws are a perfect fit for my project. Being able to by as few or as many as I wanted is a serious bonus!
