مسامير عربة مقاس 5/16-18 × 1-3/4 بوصة | محززة بالكامل | فولاذ عادي درجة A307 (1125 / عبوة)

The square neck under the head grabbed the wood instantly and didn’t spin a single time while I torqued them down — that’s exactly what you want from a carriage bolt. Full box of 1,125 came well-packed and the threading was clean all the way along, so every nut went on without catching.

Bought a full box for a deck repair project and these fully threaded bolts held strong without any slippage. The rounded head sits flush and looks clean once installed.

The square neck grabbed perfectly into the wood, no spinning at all while I tightened them down. For 1,125 pieces this box is a solid deal.
