Customer Reviews (4.6 / 5 · 5 reviews)

Mia ★★★★★

Swapped out the old screws on my deck railing near the pool, and the 316 stainless steel hasn't shown a single spot of rust after a month of splashing. The oval head sits flush and looks much cleaner than the pan heads I used before.

Scarlett ★★★★★

These are holding up great on my boat's railing after a full season in saltwater, not a speck of rust. The 316 stainless steel feels solid and the oval head gives a clean, low-profile finish.

Avery ★★★★★

The Phillips heads seated perfectly without stripping, and the 316 stainless is exactly what I needed for coastal use. These are the first oval heads I've found that don't snag on nearby parts.
