مسامير عربة 1/2-13 × 9 بوصة | ملولبة جزئيًا | ستانلس ستيل 316 (25/عبوة)

The square neck grabbed the wood immediately when I sank them into my deck frame, no spinning or fussing with a wrench. 316 stainless is a relief too, since these are going to sit outside in the salt air.

These bolts tightened up perfectly on my dock repair, and the square neck really does lock them in place without spinning. The 316 stainless feels heavy-duty and should hold up well by the water.

Tackling a boat trailer rebuild and the square neck under the head on these is a lifesaver—it really grabs the wood and makes tightening a breeze. The extra corrosion resistance from the 316 stainless was exactly what I needed for the saltwater environment.
