Key Takeaways
- Includes M4, M5, and M6 sizes.
- Expandable petals form a rear-panel anchor.
- Zinc-plated carbon steel construction.
Three Common Sizes
The assortment includes M4, M5, and M6 button rivet locking nuts. That range supports several common screw sizes across fastening, repair, and assembly work. The Amazon listing identifies the package color as 15PCS, but does not provide a size-by-size quantity breakdown, so buyers should confirm the assortment details before ordering.
Expandable Petal Grip
Each insert uses an expandable, petal-shaped body designed to open behind the mounting surface. This creates a stable threaded anchor after installation, according to the product description. The design is especially relevant when a panel’s rear side is inaccessible, because the fastener is inserted from the accessible side rather than paired with a conventional loose nut.
Material and Application
The inserts are made from carbon steel with a zinc-plated finish. The listing describes this construction as suitable for everyday use and helping resist moisture. These fasteners are positioned for one-side panel fastening, repairs, and assembly jobs. Compatibility still depends on the appropriate hole, screw size, panel, and installation method.
Pros
