3/8-16 X 1" مسامير عربة | ملولبة بالكامل | فولاذ مقاوم للصدأ 316 (100/عبوة)

The square neck on these carriage bolts grabbed perfectly into the pressure-treated wood, so I didn't have to hold a wrench underneath. All one hundred pieces arrived with clean threading and no burs, which made assembling my mailbox post a quick job.

Used these to mount a heavy gate and the 316 stainless is already outlasting the old zinc ones I had. The fully threaded shaft made it easy to cut to exact length with a hacksaw.

The square neck grabbed the wood firmly with zero spinning while I tightened them, and the 316 stainless finish looks clean enough to leave exposed in the weather. Took about an hour to replace all the deck hinges on my trailer with these, and they haven't budged since.
