零件：兩輪滑板車 19mm 頭管螺栓與螺絲

My Flex had been rattling at the headstock for weeks and I couldn't find this size anywhere locally. Dropped it in and the whole stem tightened up solid, no more wobble on the morning commute.

Wasn't sure a 19mm bolt would actually fit my Monster, but it slid through the headstock collar perfectly and tightened up with zero wobble. My old one had stripped threads so this was a relief. Scooter feels solid again.

Fits my Flex perfectly, the 19mm length was spot on and it tightened down with no wobble at all. Shipping took a couple weeks but honestly the part was worth the wait.
