Critical Compatibility
| Configuration | Notes |
|---|---|
| M12x1.25 thread pitch | Not compatible — cross-threading will damage the hub stud; confirm pitch before ordering |
| Ball/radius or flat wheel seats | This SKU is acorn/conical seat only — a mismatched seat type will not clamp correctly and can cause wheel loosening or stud damage |
| Aluminum wheel seats | Confirm hardness compatibility — the harder chromoly nut can gall softer aluminum seat surfaces if not matched correctly |
| Limited wheel bore clearance | Acorn/conical style lug nuts generally require adequate bore clearance around the stud to seat properly — verify clearance with your specific wheel |
Common Questions
Will this fit my wheel if it uses a ball-seat or flat-seat lug nut style?
No. This specific part is acorn/conical seat only. A mismatched seat type will not clamp correctly, even if the thread pitch matches. Confirm your wheel's seat type before ordering.
What socket size do I need?
Verify against your specific application, but this style of M12x1.5 chromoly lug nut commonly uses a 3/4" or 19mm socket.
How many do I need?
Sold individually. Order one per stud — typically 4 or 5 per wheel depending on your UTV's bolt pattern, times the number of wheels you're servicing.
What's the torque spec?
Torque to your UTV manufacturer's specification for your specific hub and wheel combination. Typical M12x1.5 UTV lug nut torque ranges from 35–45 ft-lbs, but verify in your service manual — do not use an impact wrench without a torque stick.
The Obsidian Take
The AXLG1 is for the UTV owner replacing worn, stripped, or damaged lug nuts who wants real strength upgrade over standard carbon steel — 4140 chromoly, heat-treated, gold zinc finish for mud and salt resistance. Acorn/conical seat fits a wide range of aftermarket wheels.
The two checks that matter before ordering: confirm your thread pitch is M12x1.5, not the common M12x1.25 alternative, and confirm your wheel uses a conical seat — this part won't clamp correctly on a ball-seat or flat-seat wheel design.
Non-Returnable Notice: Installed fasteners are non-returnable. Confirm thread pitch and seat type match your application before ordering.
