LKSSB Self-Clinching Nuts

Broaching Standoffs – Type LKSSB

No matter how sophisticated or advanced, electronic components must be attached reliably and securely if they are to deliver optimum performance. We offer several fastener products for use with PC boards to satisfy component-to-board, board-to-board, and board-to-chassis attachment needs.

Broaching, standoffs feature a spring action to hold PC board securely without screws or threaded hardware.

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.

Broaching Standoffs – Type LKSSB data

    What Makes Broaching Nuts Unique?

    Unlike traditional threaded fasteners, broaching nuts use:

    ✅ Press-Fit Installation – No screws, soldering, or adhesives needed.
    ✅ Spring-Like Retention – The broaching teeth deform slightly when pressed in, creating a tight, vibration-resistant grip.
    ✅ Reusable Threads – Allows repeated screw insertion/removal without wear.

    Key Applications
    1. Component-to-Board Mounting – Securing heat sinks, connectors, or shields.
    2. Board-to-Board Stacking – Used with broaching standoffs for screwless spacing.
    3. Board-to-Chassis Attachment – Fastening PCBs to enclosures or metal frames.


    Why Choose Broaching Fasteners?
    ✔ No Threaded Hardware Needed – Saves assembly time.
    ✔ Vibration-Resistant – Critical for automotive/aerospace.
    ✔ Thermally Stable – No solder to melt under heat.
    ✔ Cost-Effective – Eliminates screws and complex machining.

    Conclusion
    Broaching nuts are ideal for PCB applications requiring secure, reusable, and screw-free fastening. They ensure reliable performance in demanding environments while simplifying assembly.
