Product Description

The differences from ordinary hexagonal welding nuts

The core difference between the two lies in the flange base. The Hex flange weld nut is an enhanced version of the ordinary hexagonal welding nut, featuring an integrated flange disc. This difference results in various distinctions in structure, performance, and application. Here is the detailed comparison:

Project	Hex flange weld nut	Ordinary Hexagonal Welding Nut
Bottom shape	With enlarged flange	Flat or flangeless
Pressure-bearing capacity	directly replace with flat washer	Additional flat washer is required
Welded bumps	3	3
Applicable scenarios	Cars, household appliances, thin plate structures	Thick plates, general welding
Cost	Slightly higher (with an additional flange forming)	Slightly lower

FAQ

（1）Can this kind of Hex flange weld nut be used in an automated production line (robotic welding)?

It is highly suitable. The three-point raised platform design enables precise positioning, and combined with the vibrating tray for automatic feeding, it is suitable for the robot spot welding workstation.

（2）How do you ensure that the height of the solder bumps on each batch of products is consistent?

We use the cold heading forming process, and the tolerance of the bump height is controlled within ±0.05 mm.

（3）What is the minimum order quantity (MOQ)? Is the sample free of charge?

For standard specifications, the MOQ is 1,000 pieces; for non-standard customization, it is 500 pieces. We offer free samples (2-5 pieces per specification), and the customer only needs to bear the international shipping cost.
