Customer Reviews (5.0 / 5 · 5 reviews)

Steven ★★★★★

Threads perfectly on every 5/16" stud I've tried, and the black oxide finish gives them a clean, uniform look that resists fingerprints. For a hundred pieces at this price, they're a solid value.

Elizabeth ★★★★★

The black oxide finish on these 5/16"-18 wing nuts is holding up well and looks clean against the steel. After using a handful on a rebar project, they threaded smoothly onto the bolts without any binding.

Owen ★★★★★

Finally, wing nuts that actually grip tight without stripping—the threads on these are clean and consistent through the whole pack. Used a dozen on a steel shelf frame and they threaded on smoothly, no cross-threading. For the price, having a full hundred pack is hard to beat.
