BUYING GUIDE

How to match U-nuts and SEMS bolts

Confirm the thread size

Match the bolt diameter, thread pitch and usable length with the original hardware before installation.

Check panel range

U-nuts must fit the panel thickness and align the threaded hole with the mounting point without forcing the clip.

Compare the application

Bumpers, fenders, splash shields and engine covers can use similar-looking hardware with different dimensions. Use OEM references where available.
