Three Point Welding Flange Bolt, Round Disc Spot Welding Screw

Product Introduction

Three-point welding flange bolt is a special fastener designed for sheet metal welding assembly. The unique three raised welding points on the circular flange can form three stable welding joints with the metal plate, which effectively prevents rotation and displacement under long-term vibration. The integrated cold forging process ensures high overall structural strength, no fracture during welding and load bearing. The complete standard thread on the shank can directly match nuts for component assembly after welding. The surface galvanizing treatment isolates air and moisture to avoid rust in humid working environments.

Product Advantages

1. Three-Point Welding Protrusions: Multi-point fixed welding, anti-rotation, stable positioning, no workpiece deviation.

2. Integrated Cold Forging Molding: Dense metal structure, strong tensile and shear resistance, not easy to break.

3. Galvanized Anti-Corrosion Surface: Good rust-proof performance, suitable for indoor and outdoor equipment.

4. Simplified Assembly Process: Direct welding on thin plates, eliminate drilling and tapping steps, improve production efficiency.

5. Flexible Customization Service: Custom thread diameter, shank length and flange size according to customer drawings.
