مسامير عربة 5/16-18 X 1" | ملولبة بالكامل | فولاذ عادي A307 درجة A (1625 / عبوة)

Used these for a garden bench project and the square neck kept them from spinning while I tightened the nuts. The fully threaded shaft made it easy to cut down a few for shorter connections. Exactly what I needed for the price.

The 5/16-18 fully threaded ones worked perfectly for a fence repair, the smooth head sits flush enough that nothing snags on it. For 1,625 pieces at this price, the plain steel finish is exactly what I needed for outdoor framing after a quick coat of paint.

The square neck on these carriage bolts grabbed the wood perfectly on my first fence project, no spinning at all. For a full 1625-pack at this price, I’m set for years—solid hardware.
