Review: Quality fasteners - I recently purchased a pack of stainless steel wing nuts and when they arrived I found them to be of high quality. Now that’s the only reason I’m giving the Hillman Group five stars. I am shouting out five stars because every time I purchase fasteners from them the quality is always the same..... the best! I am retired and with plenty of time on my hands I am always working on a project so when the job requires fasteners I do not hesitate to turn to the people that deliver the highest quality hardware.
Review: Great wing nut. - I like that there is much more thread than from Home Depot wing nuts (deeper hole), which should add strength to the nut when under tension.

## Features

- Wing nuts ideal for use where frequent connection adjustments/removals need to be made
- Acorn / cap nuts protect against injury by covering exposed thread
- Stop nuts prevent loosening
- Included variants range from #6-32 to 1/2"-13 in coarse thread size
