What is the Difference Between Left-Handed and Right-Handed Threads?
Question:
For rear center cap hub why right hand or left hand thread
asked by: JAMES T
Expert Reply:
Even though most threads on bolts use right-handed bolts/nuts, some special scenarios warrant a left-handed thread. When wheel accessories like the Phoenix USA Rear Wheel Center Cap - 8-1/4" Hub Diameter - Center Hole Mount - Left Thread # PXQ1020L use a left-handed thread, it is to avoid the added torque from bumps and rough terrain on your wheels. With these forces, right-handed bolts/nuts tend to come loose from those particular movements. For a hub cap, it is recommended to use a left-handed bolt/nut if the option is available (like it is on the hub # PXQ1020L).
Also, it is important to note that the threads are from the bolts that hold the cap in place; not on the cap itself.
