مسامير عربة 3/4-10 × 6-1/2 بوصة | فولاذ عادي درجة A307 (10 / عبوة)

The rounded head sits flush against the wood with zero snagging, and the square neck locked into the timber the moment I torqued it down. Used a dozen on a pergola base and every single one held true without spinning.

The square neck grabbed perfectly in the wood, no spinning at all when I tightened the nut. Build quality is solid for plain steel, and the 6-1/2 inch length was exactly what my project needed.

Took a while to find these in this length, and they're solid for timber framing work. The square neck seated firmly in the wood with a couple taps, so no spinning when I torqued the nut down.
