Customer Reviews (4.8 / 5 · 5 reviews)

Charlotte ★★★★★

Had to swap out some hardware on a saltwater dock fitting, and these 316 stainless heads are holding up exactly as expected in the harsh environment. The full threading made it easy to get a solid bite into the flange, no stripped threads or fuss.

William J. ★★★★★

The threading is clean and the 316 stainless feels substantial in hand—no burrs or rough edges. I used these to secure a piece of equipment on a trailer and they drove in smoothly without any binding. Solid choice for anything that needs to handle a load without corrosion worries.

Hazel ★★★★★

I needed heavy-duty bolts for a dock repair job, and these 316 stainless steel heads held up perfectly under saltwater exposure without any corrosion. The fully threaded design made installation a breeze with a standard wrench.
