Key Features & Benefits:

Integrated Flange: The circular base provides a wide bearing surface, distributing clamping force evenly. This protects thin sheet metal from distortion or pull-through and enhances joint stability.

Secure Welding: Features built-in welding projections (serrations, pips, or a continuous ring) on the flange base. These ensure rapid, consistent heat concentration during resistance welding (projection or spot welding), creating a strong, permanent metallurgical bond to the workpiece.

Permanent & Vibration-Proof: Once welded, it forms an inseparable threaded insert highly resistant to loosening from shock, vibration, or thermal cycling – ideal for critical assemblies.

Simplifies Assembly: The flange often eliminates the need for a separate washer. The hex body allows for easy handling and positioning with standard tools before welding.

Single-Side Installation: Enables the creation of sturdy threaded holes where access is limited to only one side of the workpiece.

Material Options: Commonly available in:

Carbon Steel (Plain or Zinc Plated): Cost-effective for general industrial use. Zinc plating offers basic corrosion resistance.

Stainless Steel (e.g., 304, 316): Excellent corrosion resistance for harsh environments (marine, chemical, food processing).

High Load Capacity: The welded joint and flange design provide superior strength compared to many removable fasteners in sheet metal applications.

Ideal For:

Creating permanent, high-strength threaded anchors in sheet metal assemblies.

Automotive frames, brackets, exhaust systems, and body panels.

Appliances (ovens, washers, dryers), HVAC ducting, and electrical enclosures.

Furniture frames, industrial machinery guards, and agricultural equipment.

Any application requiring vibration resistance and reliable one-sided fastening.
