مسامير دبوس 7/16" × 4" | مقسى | فولاد سبائك (100 / عبوة)

Used a full pack to pin a heavy fixture plate together, and every single one pressed in with consistent interference. The alloy steel is noticeably harder than the cheap zinc ones I've tried before.

Installed these in a jig for alignment and the 4-inch length was perfect for the depth I needed. The alloy steel feels solid and I’m confident they’ll hold up under repeated use.

The hardness on these alloy steel dowel pins is exactly what I needed for jig alignment—no bending during press-fit operations. Packed neatly in a hundred-count bag, they come out clean and ready to use without any burrs or oil residue.
