مسامير تثبيت 1/4" × 1-3/8" | مقسّاة | فولاذ سبائكي (100 / عبوة)

Dropped one into my jig to test alignment and it seated cleanly with zero wobble—the 1/4" diameter tolerance is spot on. Alloy steel feels properly hardened, so these should last through a lot of shop abuse.

The alloy steel feels rock solid; I pressed them into a fixture plate and they seated perfectly without any burrs. Exactly the tolerance I needed for repeatable alignment.

Used these to pin two jig plates together and the hardened alloy steel held up perfectly under repeated clamping pressure. Every single pin in the pack measured exactly 1/4" and seated cleanly into the holes, zero binding or burrs.
