مسامير نقل 1/2-13 × 15 بوصة | فولاذ عادي درجة A307 (50 / عبوة)

I needed these for a heavy timber gate and the square neck really dug in to stop them from spinning while I tightened the nut. The plain steel finish will rust, but that's fine for my outdoor project.

The 15-inch length is exactly what I needed for a heavy timber frame project, and the smooth rounded heads sit flush without snagging anything. Every one of the 50 bolts came out of the box straight and clean, no bent threads or rough edges to fight with.

Installed a dozen of these in a new deck railing and the square neck really did grip tight—no spinning while I tightened the nut. The 15-inch length was just right for sandwiching a 4x4 post. Solid, no-frills hardware that did exactly what I needed.
