Design and Compatibility
The set uses a petal expansion structure intended to spread behind the mounting surface during installation. That design is suited to thin-panel fastening, where a threaded insert can provide a practical attachment point. The assortment is listed with M4, M5, M6 and M8 jack nut sizes, although the supplied variation is M4*20-30PCS.
Materials and Construction
Pantlon identifies carbon steel as the primary material and zinc plating as the protective finish. The product is presented for everyday workshop and maintenance use rather than a specialized single-purpose application. Official details do not provide load ratings, measurements for each size, installation-tool requirements or performance testing, so suitability should be judged against the intended fastening task.
Applications
The listing describes broad use across automotive sheet metal, equipment panels, workshops and DIY projects. This makes the fasteners relevant for repairs, panel work and general maintenance where access behind the material may be limited. Because the supplied data does not specify compatible material thicknesses or supported loads, users should verify fit and fastening requirements before installation.
