          Broaching Standoffs – Types LKFE, LKFSE

          Type LKFE and LKFSE – Broaching standoffs, threaded or unthreaded for stacking or spacing.

          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 is the purpose of broaching nut?

            Purpose of a Broaching Nut

            A broaching nut (also called a press-in nut or threaded insert for PCBs) is a fastener designed to provide a strong, reusable threaded hole in thin materials like printed circuit boards (PCBs), sheet metal, or plastic enclosures.

            Primary Functions & Benefits
            1. Creates a Durable Threaded Hole
                ♦ Allows screws to be securely fastened into materials too thin or fragile for tapping (e.g., PCBs, thin aluminum, or plastic).
                ♦ Prevents stripping compared to self-tapping screws.

            2. Eliminates the Need for Soldering or Adhesives
                ♦ Installed by pressing or hammering into a pre-drilled hole (no heat required).
                ♦ Avoids thermal damage to sensitive components (unlike solder-in inserts).

            3. Provides Vibration & Rotation Resistance
                ♦ Broaching teeth (barbs/knurls) grip the material tightly, preventing loosening under vibration.
                ♦ Flanged versions (e.g., LKFS2) add extra stability.

            4. Reusable Threads
                ♦ Unlike self-tapping screws (which wear out holes), broaching nuts allow repeated screw insertion/removal.

            5. Improves Assembly Efficiency
                ♦ Faster installation than soldered or glued inserts.
                ♦ Ideal for high-volume PCB production (e.g., consumer electronics, automotive).

            The broaching nut’s purpose is to add robust, reusable threads to delicate or thin materials without soldering, making it a top choice for PCB assembly, electronics, and lightweight mechanical designs.
