Customer Reviews (4.8 / 5 · 5 reviews)

James ★★★★★

The square neck grabbed perfectly into the wood beam without any spinning, which made assembling everything solo much easier than I expected. These bolts feel solid and the stainless finish looks clean and professional.

Ella ★★★★★

Used these bolts for a dock repair last weekend and the fully threaded length made installation a breeze. The 316 stainless steel feels solid and didn't show any rust after a week in saltwater.

Emily ★★★★★

The square neck really grabbed into the wood perfectly, no spinning at all during installation. These 316 stainless bolts feel much heavier and more corrosion-resistant than the zinc ones I've used before, exactly what I needed for the dock repair.
