David ★★★★★

The Phillips drive grabs the bit nicely without slipping, even when tightening these into aluminum framing. I also appreciate that the 18/8 stainless is non-magnetic, which helps keep metal dust from sticking during assembly.

Mia H. ★★★★★

I needed a bunch of these for a boat railing repair, and the threads caught perfectly with no binding. The 304 stainless steel feels heavy-duty enough to handle saltwater exposure without rusting.

James ★★★★★

Needed some long corrosion-resistant screws for a boat railing project, and these 4-inch 18/8 stainless steel ones are holding up great in the salt air with that non-magnetic property. The Phillips heads drive in nicely without stripping, and the 100-count pack was perfect for finishing the job.
