مسامير عربة 1/4-20 × 2-1/2" | بخيط كامل | فولاذ عادي A307 درجة A (1000/عبوة)

Used a full box of these on a treated lumber project and every single one seated flush without stripping. The fully threaded shaft gave plenty of grip, even in the denser knots.

The square neck grabbed tight into the wood on my deck repair, no spinning at all. These bolts feel sturdy and consistent across the whole bag, exactly what I needed for a big job.

The square neck grabbed instantly into the treated lumber I used for my fence posts, so no spinning while I tightened them. Having a full 1,000 count package is great for a large project without needing to run back to the store.
