I also see I need tithe bolts for the mopar hitch and checked threads on the two attached nuts and they are 12mmx 1.50 according to my thread gauge and you also mention above that spec. But all the bolts listed clearly say they are 12mmx 1.75 thread. so what do we do?
This is a common point of confusion because Jeep uses different thread pitches for different parts of the chassis, but for the trailer hitch receiver, the specifications are very specific.
The discrepancy you're seeing likely comes from the difference between M12 Coarse and M12 Fine threads.
While your gauge may be reading 1.50, the factory Mopar specification for the hitch mounting bolts on a 2007–2026 Wrangler JK and JL is actually M12x1.75.
M12x1.75 (Coarse): This is the standard hitch bolt pitch. If you are using the factory-welded nuts inside the frame or a "nut strip," they are almost certainly threaded for $1.75.
M12x1.50 (Fine): This pitch is commonly used on suspension components (like control arms) and wheel studs, but it is rarely used for hitch-to-frame mounting on Jeeps.
The "Thread Gauge" Trap: It is very easy to misread 1.50 vs. 1.75 on a handheld gauge if there is any rust, paint, or debris in the threads of the nut. Even a slight misalignment can make the 1.50 blade feel like it "fits" better than it actually does.
The Mopar M12x1.75x110 Bolt is the official OEM hardware for this application for several reasons:
Length: At 110mm, it is long enough to pass through the hitch, the bumper beam, and the frame to engage the nuts fully.
Strength: These are typically Grade 10.9 bolts, which are required for the sheer and tongue-weight forces involved in towing.
Fitment: This specific bolt (Part #06104246AA) is cross-listed for both the JK and the JL for the hitch and the rear tow hook.

Will these bolts work for the Rubicon 10th Anniversary hitch and bumper?
Yes, they will. Thanks for your inquiry.
Michael P.
Is this price for 1 bolt?
Yes, it is
Chris B.
Will these bolts work on a JL hitch? I bought the Mopar hitch not realizing it didn’t come with mounting hardware.
The description says they’re for JK hitches and something else on the JL
Yes this can be used for the JL hitches as well.

Nuts included?
No, the nuts are not included, for most applications, the nut is welded to the frame or hitch, otherwise they are serviced with the assembly. If you simply need to source a nut, the threads are M12x1.50 which are common
Ronald R.
What size socket is needed for this bolt?
19mm
Keith W.
Do you know what strength class bolt this is? 8.8? 10.9? Other? Thanks.
This is a 10.9 bolt
