مسامير عربة 3/8-16 × 1-3/4 بوصة | ملولبة بالكامل | فولاذ مطلي بالزنك من الدرجة A307 (150 / عبوة)

The zinc plating is holding up nicely after a week of outdoor use on a pergola, and the fully threaded shaft made driving them through pressure-treated lumber a breeze. Bag was packed tight, all 150 counted straight out of the box.

The square neck under the head grabbed the wood instantly when I tightened them, so no spinning or cursing with a wrench. Five dozen went into the swing set frame and the zinc finish looks clean even after a couple of rainy weekends.

The square neck grabbed perfectly into the wood on my trailer deck, so I didn't have to fight with a wrench to keep them from spinning. These are solid zinc-plated bolts for the price, and the full threading made fastening the 1-3/4" length a breeze. Just what I needed for the job.
