أجهزة RAM® المعدنية: مقبض، مسمار وزنبرك لأذرع المقبس من الفئة C

The metal knob feels much sturdier than the original plastic one, and the Jam Nut keeps it from loosening over time. It threaded onto my C size arm perfectly with no issues.

I've been using these arms for years and finally got tired of the plastic knob loosening up on bumpy roads. Swapped in this metal replacement along with the jam nut, and it hasn't budged once. Feels like a proper upgrade for a few bucks.

The metal jam nut feels much more secure than the old plastic one, and the threads on the bolt were perfectly clean out of the box. Installation took about ten minutes and my C size arm is now rock solid with no wobble.
