Common questions
What does open end mean?
The top of the nut is open, so the stud can pass through instead of being capped. That makes open end nuts a practical choice when studs run a little long, and it lets you see full thread engagement at a glance.
Which set size should I pick?
Match the count to your lug count: 16 pieces covers a 4-lug vehicle, 20 covers 5-lug and 24 covers 6-lug. Every option ships with a key, and extra keys are available as an add-on if you want a spare for the toolbox.
