Ordered a spare set after our playhouse got reassembled and a couple of the originals went missing. These 5/16 cap nuts threaded on cleanly and sit flush against the plastic, so nothing wobbles anymore.

I lost one of these while taking apart my kid's playhouse and figured I'd be stuck hunting for a match. This replacement threaded right on and tightened down snug, same matte black finish as the originals. Two extras in the pack now, so I'm covered next time.

Fits perfectly on the 5/16-inch threads, and the black finish matches the rest of the assembly without standing out. Arrived quickly and did the job for a repair I thought would need a whole new piece.
