실린더 상단 나사

Exactly the shape and threading I needed to get my traction device working again — the fit is snug and it screws on without any wobble. Feels like a quality spare part, not a flimsy knockoff.

The threads on this replacement top screw lined up perfectly with my device's cylinder, so the whole assembly feels solid again. Whoever engineered this knew exactly what the original part needed to be. Honestly, it's the most seamless fix I've had with any spare component.
