2インチアダプター 大型機械加工つまみねじ3個付き (ADA2003A)

I was worried about my heavy CCD setup slipping, but the CNC machining on these thumbscrews grips perfectly without any play. The threads engage smoothly and really lock down the adapter.

These thumbscrews are chunky and grippy, so tightening the adapter feels solid even with gloves on. The CNC machining is clean with no sharp edges, and it held my heavy camera setup dead-center without any shift during a long imaging run.

The threads on these thumbscrews are buttery smooth and grip my camera perfectly. The machined finish gives a much more precise feel than the stock adapter, and my heavy setup stays centered without any slip.
