p.1 #1 · p.1 #1 · nikon 70-200 VR tripod collar lock screw -- mine fell off


Hi All,

I was out with my son on a Cub-Scouts camping trip this weekend. We went hiking and durring the hike the tripod collar lock screw fell off but I did not notice until we got back to the camp site ... I thought it was a captive screw and would not fall off, but somehow that mechanism failed and it indeed fell off.

The thing now is I need to replace it. Any idea where to get a replacement? I can't seem to find anyone whom sells them.

Cheers,
Andre

Hmm, mine does seem to be captive. I sure don/t want to try and force it off though it feels like I might be able to do just that. Suggest you bring the lens with you to your local hardware store and ask for a set screw or thumb screw and fiddle in the bins till you find one that fits. It won't have the fancy top knob on but it won't cost 20 bucks either. The threads should be a standard size. The tripod mount screw is a 1/4-20, that will be a place to start.

Nikon won't sell them any more, so it won't be $20, it would be a trip back to the factory repair center.

I vote with Neddie - see if you can't find a knob with set screw at the hardware store.

Tell them you're looking for a knurled black plastic thumbscrew. I'll bet that your local Ace Hardware has them for around $5. You'll never be able to tell the difference.

If it is like the locking screw for the 80-200, you probably won't find a replacement in the USA as it is metric, M5 thread.

It should also have an E ring groove in it, the device that captivates it.

Oh dear! You're right, there's no way you can find metric threaded fasteners in the US... What COULD I have been thinking?

Andre, looks like you're going to have to make a trip to Japan to fix this. Can I come with you?

And if all you need to do is keep the thing from rotating then a set screw without a groove will work just fine. The e-ring is obviously broken and gone or the screw wouldn't have fallen out in the first place. You don't have to be McGiver to make this work.

This is exactly what Thom Hogan calls "customer antagonistic."

+10, I would agree. For a simple set screw, this is something that should be in the standard parts list and available for years ... in fact, it should be standard part used across designs.

--------------------------
I think you are correct, the only caviat being is that there is an internal screw that must be connect with and the outer threads that hold the knob in place. So the set screw is male on the outside and female on the inside with two different threads ... not an easy thing to find.

I wonder if there is a second source supplier?

Not sure I quite follow your description of an androgynes set screw but have a look here:

I've had good luck getting oddball hardware from these guys.

Problem SOLVED!!! It is not a funky screw size, but is the same thread as all the camera mount screws for plates and brackets. The screw for my Black Rapid strap fits perfectly and is just the right depth. I was planning on getting an extra Black Rapid connector, so now I'll just order two! A $5 solution.

The inner screw I was talking about appears to be there as a plunger for the set screw to push on and not for the set screw to screw into. It is connected to a plate that pushes on the lens barrel as opposed to the set screw gouging the lens barrel. A good design if the set screw had not come off.

I have the same problem - sort of . I have the screw . I don't know if it broke off or what but it won't lock the collar. I may just be paranoid here. Does the screw just ride against the lens body or is there a part that was lost . Maybe something the screw went into that helped lock the collar ? Andre said something about a plunger ? I know i can get a thumb screw just don't want to screw up the body .I tried to find a diagram online just to see what's under the collar - no luck . Any thoughts ??
