Lock Nuts, 6-32 (4) (DUB171)

Zinc-plated nylon-insert lock nuts are designed to prevent fasteners from loosening in vibration-prone applications, making them a reliable choice for hobby builds and model hardware.

These nuts use a nylon insert to bite into the bolt as you tighten, creating a secure lock that resists unscrewing over time. They come in a four-pack and feature a corrosion-resistant zinc finish, making them suitable for RC models, aircraft, drones, and other projects where dependable fastening matters.
