Hey Rich. The Swagman Anti-Rattle Hitch Lock item # S64027 has a 5/8" x 11 thread pitch.

If you're needing a locking anti-rattle hitch lock with a M16 thread pitch, you'll want the Threaded Anti-Rattle Hitch Pin Lock item # e99047. It has a bolt thread size of M16 x 2. This hitch pin has a 5/8" pin diameter, an inside pin span of 2-5/8", and measures 6-1/2" overall.

What are you needing a locking anti-rattle hitch pin for?

I have an extra wide 2" receiver on my truck. I need a pin that is at least 4.5" of free space between the ends. I am trying to put on a Cravot bike rack, but they only have regular size pins.

@Rich We do not have a threaded or standard hitch pin with that long of a usable span. The longest one we have is the Lets Go Aero 3" Anti-Rattle Hitch Lock - XXL Stabilizer w/ Keys item # LGA32ZR. It works with 2" and 2-1/2" receivers and has a 4-3/8" usable span.
