I`m using BK 7001HVs in my TSA 600Ns, and the diameter is 3mm. I believe the length is 6mm, but not 100% sure. I would pull one out and measure it, but I`m not using the screws that came with my servos. TSA helicopters require longer servo screws because of the servo supports. Also, the screws that come in Align DS610s are the same size as the ones that come with the BKs.

 

Thanks Geena
I had heard that 610's used the same screw ... Have some of those at home, so I tried the fit last night and it seemed a little tight. I only used my fingers and could only get it about 2 turns in .. Could have been loctite residue in the thread .. Just don't want to force the wrong thread into my new babies

 

I was running 610s on one of mine before replacing them with BKs. I used the same screws I had in the 610s , and they were a perfect fit. I`m sure if you clean the screws good with alcohol, they will run right in

 

Thanks
