Check Before You Order Some fitment details only your vehicle can tell you.
The vehicle list above confirms your year, make and model. The points below are not part of that list — they depend on the wheels and hardware currently on your vehicle. Please verify them before ordering.
Why It's Built Different Performance you can torque down. Bolts-To-Nuts Conversion For Lug Bolt Hubs
Threads into the factory lug bolt holes and turns the hub into a stud-and-nut setup, so the wheel hangs on fixed studs instead of being balanced over an empty bolt hole.
M14x1.5 Wheel-Side Thread - Your Choice Of Nuts
The stud converts the wheel side to M14x1.5, so any M14x1.5 lug nut that matches your wheel's seat runs on it; wheel-side nuts are not included with these bare studs.
M3 Allen Key Drive In The Stud Tip
An internal M3 hex in the tip seats the stud snug with a thread locker, and because the drive sits inside the stud, the wheel-side threads stay untouched during install.
SCM Carbon Steel Body
SCM Carbon Steel shanks carry the wheel load while the lug nuts, torqued to your vehicle spec, provide the clamping force; the stud body is only seated snug, not torqued.
Faster Seasonal Wheel Swaps
With studs fixed in the hub, the wheel locates itself before any nut is started - less cross-thread risk and quicker tire changes every season.
How to Install 3 steps to torque.
Follow the sequence below ? fitment is everything, so read Step 1 carefully.
01 Clean And Prep Bolt Holes
Remove the factory lug bolts and clean the hub threads so each stud seats on dry, oil-free threads, then apply a thread locker to the hub-side end of the stud.
Repair worn or damaged hub threads before installing any stud. 02 Seat Studs With M3 Key
Drive each stud into the hub with the M3 Allen key in the stud tip until it sits snug against the hub, then let the thread locker set per its instructions.
Snug only - torquing the stud body can strip the hub threads. 03 Mount Wheel, Torque Nuts
Hang the wheel on the studs, start all M14x1.5 lug nuts by hand, then torque in a star pattern to your vehicle spec and recheck torque after the first drive.
Clamping force comes from the lug nuts at vehicle spec, not from the stud body. 01 / 4 4 photos in this guide — tap the arrows or dots to see every step Important Fitment Notice Before You Buy:
- for factory lug bolt hubs - each stud replaces a lug bolt
- wheel-side lug nuts must be M14x1.5 and match your wheel's seat, the nut-to-wheel contact shape
- nuts are not included with bare studs
- the stud count for this listing is in the title
Install:
- seat studs snug with the M3 Allen key and a thread locker - never torque the stud body
- clamping force comes from the lug nuts torqued to vehicle spec
- recheck torque after the first drive
's compatibility list matches by vehicle only. The wheel-side facts above — seat geometry, hole clearance, installed depth and usable thread engagement — still need your own check. Message us through before ordering if anything is unclear.
Why ESPLUS Clarity before checkout.
Wheel hardware is fit-critical. Our listing structure keeps the evidence a buyer needs in the order it should be checked.
Specification First
Thread, seat, dimensions, finish and quantity are organized for direct comparison.
Fitment in Two Layers
Vehicle compatibility and wheel-specific hardware checks are presented separately.
Component-Level Detail
Combination listings keep each component's quantity, gallery and technical data distinct.
Pre-Purchase Support
Message us through with your year, model, wheel and current hardware details.
Questions, answered Check the details that decide fit. Will this wheel hardware fit my exact vehicle?Start with the vehicle compatibility section, then read every fitment note. Compatibility data does not replace wheel-side checks such as seat type, hardware dimensions, hole clearance and usable thread engagement. How do I confirm thread pitch and seat type?Compare one piece of your existing hardware with the technical data and the Check Before You Order images. Match the thread on the vehicle side and the seat geometry required by the wheel. What should I verify on aftermarket wheels?Confirm the wheel's seat profile, fastener-hole diameter, tool clearance, installed depth and required engagement. These wheel-specific facts are not established by year, make and model alone. What torque specification should I use?Use the vehicle or wheel manufacturer's applicable specification and installation procedure. If the two sources differ or the application is modified, consult a qualified installer before installation. Where can I find current shipping and return terms?Use the Shipping, delivery and Returns sections of this listing as the current order-level terms. Those listing controls take priority over general informational text. Shipping · Returns · Fitment Order terms, kept current.
