1/8" X 3/8" 彈簧銷 | 開槽 | 鋼（4000/包）

Packed 4,000 pins in one box is exactly what my shop needed for ongoing assembly work, and the steel construction feels solid enough to handle constant vibration without loosening. They drove in cleanly with no bending or burrs, which saved me a ton of time.

Just finished assembling a batch of brackets and these steel pins held perfectly under heavy side load with no slipping. The 4000-count package means I won't need to reorder for months.

Got our jig setup tightened up with these — the steel finish holds up well under repeated vibration without slipping. For the price per pin, getting four thousand in one box was a no-brainer for our shop.
