Heininger Black 5/8" Diameter Pin 6001 Advantage Threaded Receiver Trailer Hitch Lock Designed Products

High quality locking pin. Super inexpensive but works fine. Same as Swagman but length may vary. One poster rated it low but looks like they had a thread mismatch resulting in stripped threads. This is SAE 5/8 bolt with 11 threads per inch. Head is 7/8" across flats. It is a bit long but fit our hitch fine.

We purchase this lock to work with our Heininger 2200 Advantage 2" SportsRack glideAWAY 4 Bike Rack Carrier and it works perfectly. You just have to be careful that there is room for the lock mechanism on your hitch (ours barely fit).Another reviewer indicated this is not an effective anti-wobble lock but I believe that they are mistaken. The threaded pin by itself is not an anti-wobble device but when screwed into the nut that is installed inside the rack's receiver unit it becomes a very effective anti-wobble system. I believe this lock would work with any 5/8 threaded anti-wobble system provided the thread size is the same. Both the Carrier and the Lock met all of our expectations (ability to move bikes back while we get into rear of our Honda Pilot and an effective lock to keep someone from unhitching and taking everything).

Purchased in conjunction with the Heininger 6000 Hitch extension in which it is specifically designed for; however, it is not compatible and is too small in diameter. Does not fit as designed. It works as a lock, but the threaded portion of the bolt is much too small for the female threaded end and does not tighten, thus making this useless. Returned

Does the job. Threads are 5/8” by 11 TPI, fairly standard. Fits my 2” hitch Yakima 4 bike rack perfectly, and reduces wobble. Keys and lock cover might not be the highest quality but they seem to function fine, especially for the price. Would recommend.

Works great on my yakima on ramp bike rack

This lock seemed really solid, much more solid than the other lock I tried. Unfortunately, the threads didn't fit my bike rack, so it was returned. I am reviewing as 5 stars, because it really was pretty solid.

This does the job perfectly. It is worth every penny. You must have this!!Yes, you must purchase this locking trailer hitch to do the following:- Lock you bike rack to prevent theft and- This "screw-in" bolt, keeps your bike rack from wabbeling back and forth. Withoutthis "screw-in" feature your rack will sway as you drive and possibly cause shiftingin your bikes and possibly even shake a bike loose. Be sure to secure all bikes withbungy chords in addition to the racks rubber straping.

I purchased the Heininger 6000 extension and 6001 threaded hitch lock at the same time. I have not test drove it yet, but it seems to accomplish what I wanted. My bike rack now fits on my Wrangler with room to spare clearing the 12.5in wide spare on the back. I really like having more than one pin location.I was not sure if the lock thread would fit with the extension, but it does. Despite the very little clearance available around my hitch, I did get it to fit and lock. I had to insert it from the left as the hitch wire harness connection interfered with the lock when inserted from the right. I also discovered that the hitch lock on my 2in receiver Yakima rack fits the same threads as well. I may have purchased another one of these instead had I known. It would be nice to just have one key for everything.The only downside I encountered was that 6001 and 6000 were not in stock together, meaning I had to pay for shipping on both from two different Amazon affiliates.
