مقبض قفل RAM® بمفتاح مع إدخال فولاذي لأذرع المقبس من الفئة C

The steel insert gives this knob a solid, reassuring feel when I torque it down—no stripping worries like with the plastic ones I’ve had before. Threads matched up perfectly on my C size arm, so it was a straight swap.

Finally got this replacement knob for my RAM mount arm, and the 5/16"-18 thread threaded on perfectly without any wobble. The key lock mechanism gives me peace of mind that my setup won't get swiped when I step away.

The steel insert feels much more sturdy than the old plastic one, and threading it onto the socket arm was a perfect, smooth fit. It locked in place exactly as expected, so my mount is rock-solid again.
