M5×8 CD Flanged Metric Weld Stud Galvanized Compliant With GB Standards

M5×8 CD Flanged Metric Weld Stud, Galvanized, Compliant with GB Standards

1. Product Description

The M5×8 CD flanged metric weld stud is a precision threaded fastener designed for capacitor discharge (CD) welding to thin‑gauge sheet metal. It features a standard M5 metric coarse thread with a nominal length of 8 mm. The stud is manufactured from low‑carbon steel and finished with a galvanized (zinc) coating, providing good corrosion resistance and a uniform appearance. The product complies with relevant Chinese GB standards for dimensional accuracy and mechanical properties.

Available in a range of thread sizes from M3 to M10 and custom lengths from 15 mm to 100 mm (8 mm as a special order), the galvanized M5×8 CD weld stud is widely used in sheet metal fabrication, electrical enclosures, automotive components, HVAC systems, and general industrial assembly where a cost‑effective, corrosion‑resistant threaded attachment is required.

3. Key Features

• Galvanized surface finish – Zinc plating provides good corrosion resistance for indoor and mildly outdoor environments, and enhances the appearance of the finished assembly.

• CD flanged design – The integrated flange ensures consistent weld penetration, reduces spatter, and helps maintain perpendicular alignment during welding.

• Fast and clean welding – Capacitor discharge process completes the weld in 1–3 milliseconds, leaving minimal heat discoloration on the reverse side of the sheet.

• No back‑side access required – Ideal for closed sections, boxes, or assemblies where only one side is accessible, eliminating the need for through‑holes or access holes.

• Customizable length – Although standard lengths start from 15 mm, we offer 8 mm as a custom order to suit specific insulation or component thicknesses.

• Thread versatility – M5 thread allows secure fastening of nuts, brackets, or other threaded components. Also available in M3, M4, M6, M8, M10.

• Complies with GB standards – Dimensional and performance requirements meet Chinese GB/T 10433 (equivalent to EN ISO 13918), ensuring compatibility with standard CD welding equipment in China and international markets.

• Cost‑effective – Galvanized carbon steel offers a balance of performance and economy for high‑volume applications.

• Sample and small order support – Low MOQ and free samples for qualification.

4. Applications

The M5×8 galvanized CD flanged weld stud is widely used in:

• Sheet metal fabrication – Attaching threaded studs to enclosures, cabinets, chassis, and panels without drilling or tapping. Ideal for mass production.

• Electrical and control panels – Mounting busbars, terminal blocks, cable clips, and electronic components where a reliable threaded point is needed.

• Automotive industry – Fastening trim, wiring harness clips, insulation pads, and small brackets to body panels or structural parts.

• HVAC systems – Fixing insulation materials (rock wool, glass wool), duct liners, or support brackets onto air handling units and ductwork.

• Appliance manufacturing – Internal fastening points in washing machines, ovens, refrigerators, and other white goods.

• General industrial assembly – Replacing rivets, weld nuts, or adhesive bonding with a fast, clean, and strong welded stud.

• Lighting and signage – For mounting LED drivers, junction boxes, or sign frames to metal backing plates.

5. Flange Design (EN ISO 13918 / GB/T 10433)

The integrated flange (FD = 6.5 mm) offers multiple benefits:

• Increased welding contact area – Distributes welding force evenly, reducing electrode wear.

• Self‑alignment – Helps keep the stud perpendicular to the workpiece surface.

• Fillet formation – The flange edge melts slightly during welding, forming a small fillet that increases joint strength and fatigue resistance.

6.Material Advantage – Galvanized Steel

Low‑carbon steel provides good weldability and mechanical strength. The galvanized (zinc) coating protects against rust during storage and handling and offers moderate corrosion resistance in indoor or mildly humid environments. For CD welding, the zinc coating is thin enough to allow stable electrical contact; a small amount of zinc vapor may be released during welding, but this does not affect weld integrity. For severe corrosive environments, stainless steel or additional post‑weld coating is recommended.
