Introducing examples of NG (not good) usage of studs! What happens when they are pressed into the edge of a board?
NG usage example [Cell stud edition]! What happens when a cell stud is pressed in right up to the edge of the board...? The manufacturer verified it themselves!
The distance from the center of the mounting hole to the edge of the plate is crucial for press nuts. What happens to the sheet metal if this distance is reduced from the specified value during press-fitting? The manufacturer of self-clinching fasteners (press nuts), "Sel Japan," has conducted an investigation! We provide materials summarizing data on the bulging and strength of the plate edge after press-fitting. ★ For details, please download the "NG Usage Example (2) / Press-Fitting to Plate Edge ST Edition" below ★ ■ Product Used ST-M3-10 ■ Distance from the center of the mounting hole to the plate edge (catalog value: 5.6mm) In this document, we have verified the following four patterns: 1. 5.6mm 2. 5.1mm 3. 4.6mm 4. 4.1mm * The test results are for reference only. There may be slight variations depending on the measuring instruments and usage conditions. * For more details, please download the PDF or feel free to contact us.

basic information
【Main Types】 ▶ Self-fastener - A conventional method where a self-fastener (pilot) is inserted into a pre-drilled base material and the knurled part is pressed in. ▶ Self-stud - A method that provides high fastening strength. - The surface of the base material on the flange side is finished flat, eliminating the need for post-processing such as polishing. ▶ Self-spacer - When pressed into the pilot hole of the base material, it stands vertically and the surface is finished flat. 【Points】 ▶ No special qualifications are required for pressing! Anyone can easily install it. ▶ No variation in quality! *For more details, please refer to the PDF document or feel free to contact us.
