Crimping Nut

Crimping Nuts are specialized fasteners designed to provide a secure threaded connection in thin sheet materials where traditional tapping methods are not possible. These nuts are mechanically crimped into the material, offering strong load-bearing threads while preventing rotation and pull-out.

Industrial Applications

Crimping Nuts are widely used in:

  • Electrical panels and assemblies: Provide firm threaded connections in thin sheets where conventional nuts can’t be used.
  • Automotive components: Ensure durable fastening in lightweight assemblies such as dashboards, trims, and panels.
  • Aerospace structures: Offer vibration resistance and secure threads in lightweight alloys.
  • Consumer electronics: Used in casings, enclosures, and devices requiring compact fastening without welding.
  • Construction hardware: Applied in sheet metal and framework connections where reliability is critical.

Product Description

Crimping Nuts are permanent installation fasteners that create a robust threaded insert in soft or thin sheet materials. They are installed by applying crimping pressure that locks the nut firmly into position, resisting both torque and pull-out. This makes them an ideal solution in designs that require reliable threads in lightweight materials without compromising strength. Available in metric and inch sizes, they come in various materials and surface coatings to match both functional and environmental requirements.
