Customer Reviews (4.8 / 5 · 5 reviews)

Owen G. ★★★★★

The hex socket drive made torquing these into a tight flange a breeze, no stripping even with a cheater bar. Cup point bit into the shaft cleanly and the 316 finish hasn't shown a hint of rust after a week of salt spray.

Aurora Z. ★★★★★

Needed a cup point screw for a marine railing repair, and the 316 stainless steel is a nice upgrade from standard hardware. The hex drive allowed me to tighten these securely in a tight corner without stripping.

Penelope ★★★★★

The hex socket drive made it easy to get these screws tight in a cramped spot under my boat's deck. Even after a month in saltwater, there's zero rust on the 316 stainless steel. Definitely worth the extra cost over standard hardware.
