- Locking Tab, M8 or 5/16" Stud or Bolt
If you're tired of loosening turbo nuts, this is the solution for you. Installs around a 8mm or 5/16" stud, under the nut, one side folds down, the other up to lock the nut in place and prevent loosening under varying heat and expansion conditions.
Perfect for any smaller bolt or stud application including T25 turbo flanges, exhaust manifold fasteners, etc.
Precision cut from 304SS, reusable and a must for any turbo install.
Install Tip - when installing, keep in mind the direction of rotation for the nut, install and bend the tab to prevent loosening or counter clockwise rotation. (see installed picture)
