صامولة قفل المقبض 1/4 × 20 (180084)

Was worried a generic nut wouldn't sit flush, but this one threaded on smooth and snugged the handle down tight. The 1/4 x 20 size was exactly what my old unit needed.

The threads matched up perfectly on the first try, which rarely happens with replacement hardware. It's holding the handle on my kid's wagon steady after a few weeks of daily use.

Ordered this to replace the lock nut that went missing off my kids' playset handle, and it threaded on perfectly. The 1/4 x 20 size matched the original exactly, so the handle's solid again. Took two minutes to install with just a wrench.
