I am not - all of the threads are engaged, just barely admittedly, but that counts in my eye. Any more threads/stud sticking out beyond that have no function other than being along for the ride.
At least that's my view, I am not an engineer in any formal sense. If I were to do the brakes on the rear end someday I am sure I'd probably find some slightly longer studs just because, but until then I'm comfortable.
FYI - Regarding how many threads should "stick out" (protrude beyond the nut), common recommendations drawn from industry practices aligned with ASME standards and Machinist's Handbook-related calculations include:
- Minimum protrusion: At least 1–3 full threads beyond the nut (often 2 as a standard).
- Maximum protrusion: Preferably no more than 5 threads; do not exceed 10 to avoid waste, interference, or safety risks like snagging or injury.
- Reasons:
- Ensures full nut engagement on completely formed bolt threads (the first 1–2 threads on a bolt are often incomplete or chamfered, reducing strength if the nut stops there).
- Provides visual confirmation during inspection that the bolt is fully through the nut without short-threading.
- Excessive protrusion wastes material and can create hazards or clearance problems.
- Insufficient protrusion risks reduced joint strength or failure under load.
