Size Assortment
The kit includes M4, M5, and M6 button rivet locking nuts, providing a selection for common fastening, repair, and assembly jobs. The assortment is identified as 15PCS, giving buyers a compact set rather than a single insert size. Its one-size listing refers to the product variation, while the fasteners themselves cover three metric dimensions.
Petal Expansion Design
Each insert uses an expandable, petal-shaped body. Once positioned through a mounting surface, the body opens behind the panel to create a threaded anchor. This design is especially relevant where access to the back is limited, because the fastener is inserted from one side instead of requiring a separate nut to be held behind the material.
Material and Finish
The inserts are made from carbon steel with a zinc-plated finish. According to the supplied product information, this construction is intended for dependable everyday use and helps resist moisture. The kit is positioned for practical fastening and repair applications, but the available data does not specify load limits, compatible material thicknesses, or installation tool details.

Buying Advice
