          Installation:
          Must always be carried out using a squeeze action-nevr a shock loadPunch a hole in the metal sheet to the size recommended in our technical data tableDe-burring of the hole is not recommended.Apply pressure to the head of the fastener sufficient to totally embed the clinching ring aroundthe entire circumference and bring body in contact with the sheet.Insert fixing screw or bolt from side opposite to the fastener body.

            What are broaching  nuts fasteners?

            Broaching nuts (also called press-in nuts or threaded inserts for PCBs) are specialized fasteners designed for secure mounting onto printed circuit boards (PCBs). They provide durable, reusable threaded holes for screws, allowing components, heat sinks, or enclosures to be attached to the board.

            Key Features of Broaching Nuts (LKF2 / LKFS2 Types)
            ♦ Material: Typically brass or steel, often with nickel or gold plating for corrosion resistance.

            Design:
            ♦ Broaching teeth (barbs or knurls) – Grips the PCB hole when pressed in, preventing rotation or pull-out.
            ♦ Internal threading – Accepts machine screws (e.g., M2, M2.5, M3).
            ♦ Flange option (LKFS2) – Provides extra stability and prevents over-insertion.
            ♦ Installation: Pressed into a pre-drilled PCB hole (no soldering required).

            Advantages of Broaching Nuts
            ✔ Strong mechanical retention (better than solder-in threaded inserts).
            ✔ Reusable threads (unlike self-tapping screws, which can wear out PCB holes).
            ✔ No heat or soldering needed (avoids thermal damage to PCBs).
            ✔ Vibration-resistant (unlike plastic inserts).

            In-Sail Fastener
            ✔ Company: In-Sail Fastener (likely a manufacturer/distributor of broaching nuts).
            ✔ Products: Likely supplies LKF2 (standard) and LKFS2 (flanged) broaching nuts in various sizes (M2, M2.5, M3, etc.).

            Broaching nuts are ideal for PCB applications requiring strong, reusable, and solder-free threaded mounts. They outperform self-tapping inserts in durability and are preferred over soldered inserts in high-vibration environments.
