براغي عربة 1/4-20 × 3-1/2 بوصة | ملولبة بالكامل | فولاذ مقاوم للصدأ 316 (50 / عبوة)

Bought these for a marine dock repair and the 316 stainless steel held up perfectly against the saltwater spray during the first storm. The rounded head sits flush on the wood, and the square neck kept them from spinning while I tightened everything down.

The square neck grabbed perfectly in the wood on my dock project, and the full threading is great for stainless. These bolts should hold up for years outdoors in the salt air.

The 316 stainless steel feels like it will hold up well outdoors, and the square neck does a good job keeping them from spinning as I tighten them. Only wish the package had a few more bolts for the price.
