MS16555-646 | مسامير دبوس عسكرية | فولاذ سبائكي (100 / عبوة)

The alloy steel is noticeably harder than the generic pins I've used before, which made pressing them into jig holes feel much more precise. All 100 pins in the pack were consistently sized and slid through my alignment fixtures without any binding.

Mated two jig plates this morning and the alignment was spot-on, thanks to the alloy steel holding its tolerance. No burrs or stuck pins, just a clean press fit every time.

I needed a set of pins that could hold two heavy steel plates in perfect alignment, and these alloy steel dowels did the job without any measurable play. The 100-pack is great, as I've already gone through a few spares for other projects.
