Radial joint protectors thread question

I got some radial joint protectors and although they didn't screw in tight, they still screwed in. I didn't think much of it as it still covered the joint.

Recently I ran into someone that had radial joint protectors very similar to mine except the threading was different. I took a picture:

and a video of my joint looseness

apologies from my cat for trying to drag the camera off the table.

i'm only worried that if i screw it on too tight or too loose, it can damage something. am i nit picking or are some radial jps just like this?

i offered to trade but he said no :(

In the pic which one is your jp?
The one on the left is a radial, the one on the right looks like a 3/8x10 or 3/8x11.
 
mine is on the right. heh i swore i had posted this thread and then i didn't see it so i wrote another one. turns out i pm'd the seller first accidently, who told that they are just different manufacturers and they both do the same thing, and he sells a lot of stuff on here.

are you guys sure? do 3/8-10's successfully screw onto and into radials like in the video just with play or would they cross thread / no screw in right?

edit: i believe him, looking at 3/8-10 jp's, the threads look closer together (i believe i heard radials are around 8.5 threads per inch):

I've just tried my 3/8x10 jp's on my radial cue and theres no way they fit, they go on for about a 1/4 turn then get stuck. If you just need 1 shaft and 1 butt jp I've got a spare set I'll send you, just pm me your address.
 
Your JP's are for a Radial Pin. They are the right diameter and pitch, which is different than the 3/8x10.

They are not machined with the actual profile of the Radial pin, which really doesn't matter for a joint protector. The one on the left in your picture is actually machined to the Radial profile, and will cost more.

All you are really trying to do is protect the end of the cue shaft, so there is no need for it to be a tight fitting thread. The only way your JP could damage the thread would be if you tightened it real real tight. You would probably need pliers to do this. Then it may deform the threads in the cue shaft, but so would the other JP if you tightened it that tight.

It's just a different manufacturer of the Joint Protectors!

Good explanation Royce. I sold him the set and they are a Radial JP. They are 2 different MFG that he is looking at. The one on the right is not 3/8x10 it is considered a 3/8x8 which is the thread size of the radial screw. Thanks Troy
