Flange Nut, 5/16"-18

The threads on this 5/16"-18 flange nut caught cleanly right from the start, and that wider flange face gave my workholding setup a much more solid grip. I used a few to secure a T-slot fixture, and the extra bearing surface really made a difference in holding pressure without digging in.

The 11/16-inch flange surface really kept this nut from sinking into softer wood during my clamping setup. Threads engaged smoothly with no binding on the bolt. It's a solid piece of hardware for the price.

The 5/16"-18 threads grabbed cleanly and the wider flange held my workpiece steady without needing a washer. This is the kind of simple part that makes clamping setups feel rock solid.
