Description

Automotive manufacturers put aluminum heat shields under cars, secured with steel nuts and bolts. In the presence of road salt, these shields can come loose and rattle.
This "nut" is designed to be force-threaded on to whatever part of the bolt still remains, then "screwed" tight until the aluminum shield no longer rattles.
Let me know if it worked for you!
