HOLO-KROME 02021 Goupilles 4mm X 20mm | Acier allié (100 / Pqt)

The chamfered ends made sliding these into tight alignment holes noticeably smoother than with standard dowels. They seated with a satisfying, snug press fit that held firm during assembly. Exactly the precise alignment I needed for mating those stamped parts.

Finally, dowel pins that actually seat properly with a consistent press fit — the chamfered ends make all the difference during assembly. These 4mm pins are ground so smoothly they slide in without any binding. Exactly what I needed for precise jig alignment.

Was expecting a bit more surface finish consistency across the batch, but the hardened alloy steel feels solid and the chamfered ends definitely helped with alignment during assembly. Four stars because the press fit in my jig block felt slightly tighter than other 4mm pins I’ve used.
