零件：兩輪滑板車 44mm 螺栓與螺絲

Replaced the worn folding block bolt on our Flex and the wobble in the stem is completely gone. The 44mm length threaded in perfectly, no forcing needed. Nice to have the exact part instead of guessing at the hardware store.

My son's scooter fold hinge was rattling like crazy, and this 44mm screw replaced the worn one in minutes. Fits our Flex and the Bullet we borrowed—solid and tight now. Exactly the right part.

The 44mm size was spot on for the folding block on my old two-wheeler, and the threads went in without any cross-threading. Finally got the stem to lock up tight again.
