用在哪 / Applications

包装与批号 / Packing and Batch Code

50 pins per anti-rust bag, batch code printed on each bag. One tray of 490 pins per carton.
选型提示 / Selection Notes
销孔建议铰到 H7。锥度 1:50 的销装进去后靠锥面自锁，拆的时候用拔销螺孔，比敲出来省孔。
Ream the hole to H7. A 1:50 taper locks itself once seated; use the extraction thread to remove it, which is kinder to the hole than knocking it out.
