HOLO-KROME 02001 3mm x 8mm 定位銷 | 合金鋼 (100/包)

The chamfered ends made these surprisingly easy to press into my drill jig without any binding, and the hardened surface should hold up to repeated use. Exactly what I needed for precise alignment on a few prototype parts.

Needed a few for a jig I was building, and these 3x8mm pins seated beautifully with a consistent press fit every time. The hardening is obvious when you try to file one—tough stuff for the price.

The chamfered ends made insertion into my pre-drilled jig holes effortless, and the hardened steel feels solid for repetitive alignment work. These pins seated without any binding on the first try. Will be buying more for future fixture builds.
