Review on 🔧 20pcs Nylon PCB Circuit Board Mount Supports with 8mm Reverse Spacing Height - uxcell by Saber Spencer

This stud is designed to go through a hole drilled in a substrate such as sheet metal or plastic: the substrate must not be thicker than 0.060" (1.5mm) or the spring retainers will not snap. The ideal hole in the support material is about 0.169" (4.3mm). Your printed circuit board (PCB) will be held against the "tip"- Pushed end of rack: PCB thickness should not exceed 0.063" (1.6mm). ), otherwise the spring retainers will not engage. The ideal size of a hole in a PCB to accept a "spike" is about 0.130" (3 .3mm).The 8mm gap height in the product description is the distance between the substrate and the PCB when assembled and pressed together.
