مسامير نقل مقاس 5/16-18 × 2 بوصة | خيط كامل | فولاذ مقاوم للصدأ 316 (100/عبوة)

The square neck under the head really bites into the wood, so I didn't have to worry about the bolt spinning while I tightened it. For a saltwater dock repair, these 316 stainless bolts should hold up much longer than the cheap ones I used before.

Installed these on a new wooden gate and the 316 stainless steel is already looking much more corrosion-resistant than the zinc-coated ones I used last time. The square neck seated firmly into the wood with no spinning at all during tightening.

The square neck grabbed perfectly into the wood on my new gate, so I didn’t need a second wrench to hold them still. These 2-inch 316 stainless bolts feel heavy-duty and should resist rust well near the coast.
