Joseph V. ★★★★★

Had to swap out some zinc set screws on a marine shaft collar, and these 316 stainless ones are holding up perfectly without a hint of rust. The cup point bites into the shaft nicely, and the hex socket makes installation a breeze with a standard allen key.

Madison ★★★★★

Got the 316 stainless ones for a pulley setup on a saltwater boat, and they’ve held up perfectly through a full season without a hint of rust. The socket drive is easy to seat even in tight spots, and the cup point grips the shaft like it’s supposed to.

Kevin ★★★★★

The cup point bites into the shaft nicely, and the 316 stainless gives me zero worry about rust in a damp shop. I used a dozen on a pulley setup and they cinched down tight without stripping.
