Customer Reviews (5.0 / 5 · 5 reviews)

Isabella ★★★★★

The square neck grabbed the wood instantly when I tightened these, so I didn't have to wrestle with a wrench on the other side. The 316 stainless feels heavy-duty and the fully threaded length gave me plenty of grip for a thick deck repair.

Jason ★★★★★

The domed heads sit flush against the wood and the threads bit cleanly without any galling—I used them for a cedar gate and they held up fine in the rain. 316 stainless is the reason I picked these, and so far no rust spots have shown up.

Evelyn ★★★★★

The square neck grabbed the wood immediately when I tightened these, so no spinning or cursing on the job. Fully threaded 5" length gave me plenty of grip, and the 316 stainless feels solidly corrosion-proof for outdoor use.
