M12 x 1.25 Extended Closed End Lug Nuts — 20pc Set, Aluminum

Key Features
- Extended Length - Threads deeper into studs, essential for wheels pushed outward by spacers or wide offsets.
- Closed End Design - Fully encases the stud cap, protecting threads and keeping dust and moisture out.

Frequently Asked Questions
Will these work with my wheel spacers?
Extended length is designed specifically for spacer setups and wider offsets where standard lug nuts don't reach far enough. Verify your stud length before ordering — if studs are too short, the nut won't seat properly.
Do I need any special tools to install these?
A socket that fits M12 lug nuts and your existing lug nut wrench or impact gun will work. Tighten to your vehicle's service manual spec — do not assume standard torque values.
Are aluminum lug nuts as strong as steel?
Aluminum is lighter but softer than steel, so threads can strip if over-torqued. Tighten firmly but do not force — follow your manual's specification exactly. The closed-end design protects the threads from corrosion, extending service life.
