Welding Threaded Studs M3 Stainless Steel Threaded Welding Stud with Flange

What Are Welding Threaded Studs?

Welding threaded studs are specialized fasteners designed to be permanently welded to a base material (typically metal) to create a strong, threaded mounting point. They feature:

• Threaded end: Accepts nuts or other fasteners.

• Weldable end: Flat, serrated, or flanged for secure welding.

• Types: Capacitor discharge (CD) studs, drawn arc studs, and flange studs.

Ideal for applications requiring high-strength, vibration-resistant connections where traditional bolts can’t be used.

Welding Threaded Studs: Specifications & Applications

1. Material

• Stainless Steel (304/316): Corrosion resistance for marine/chemical environments.

• Carbon Steel (Grade 4.8–10.9): High strength for structural welding.

• Aluminum: Lightweight for automotive/aerospace.

2. Surface Treatments

• Zinc Plating: Basic corrosion protection.

• Hot-Dip Galvanizing: Heavy-duty rust resistance.

• Passivation (Stainless Steel): Enhances oxide layer.

3. Specifications

• Thread Sizes: Metric (M3–M24) or imperial (#6–1″).

• Length: 10–200mm (customizable).

• Flange Options: Round, square, or serrated bases.

4. Key Applications

• Automotive: Body panel attachments, exhaust systems.

• Construction: Steel beam connections, rebar anchoring.

• Shipbuilding: Deck equipment mounting.

• Electronics: Grounding points in enclosures.

5. Excellent Case

Scenario: Securing HVAC ducting in a chemical plant.

• Problem: Standard bolts loosen due to vibration and corrode in acidic air.

• Solution: M8 stainless steel flange studs (316 grade) welded to duct seams provide:

  • Permanent, vibration-proof threads for bracket attachment.

  • Chemical resistance from passivated 316 stainless steel.

  • Flange design distributes load across thin duct walls.
