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

The hardened alloy steel feels really sturdy in hand, and the 3/8" diameter mates perfectly with my jig's guide holes. No splitting or bending even when I drove them into tight oak joints.

Checked the first few against a micrometer and every single one measured exactly 0.375" — these alloy steel pins are consistently spot-on for jig alignment.

I was worried about getting pins that weren't perfectly hardened, but these alloy steel ones feel rock solid and seated without any play. The 1-1/8" length was exactly what I needed for aligning jig parts, and the whole pack of 100 saves me a trip to the hardware store.
