Product Description

Engineered for precision and durability, these CD Studs (Capacitor Discharge Studs) in Mild Steel, M4 x 30mm, are the ideal fastening solution for fast, clean, and permanent stud welding applications. Supplied in a convenient pack of 100 units, this product is perfect for trade professionals, fabricators, and industrial workshops requiring reliable bulk stock for high-volume projects.

Manufactured from high-quality mild steel, these CD studs are designed for use with capacitor discharge (CD) stud welding machines, delivering a strong, weld-through bond in milliseconds without the need for pre-drilling, pilot holes, or visible marking on the reverse side of the base material. This makes them especially suited for applications where surface finish and aesthetics matter, such as sheet metal work, cladding, signage, and architectural metalwork.

Key Features

  • Material: Mild Steel — offers excellent strength, weldability, and corrosion resistance when coated or painted
  • Thread Size: M4 (4mm diameter) metric thread
  • Length: 30mm — suitable for medium-depth fastening and mounting applications
  • Pack Quantity: 100 studs per pack — ideal for bulk industrial and trade use
  • Welding Type: Compatible with CD (Capacitor Discharge) stud welding systems
  • Finish: Clean, no-mark reverse-side weld, minimizing surface distortion
  • Application: Suitable for thin-gauge sheet metal, stainless steel panels, and mild steel fabrication

Common Applications

  • Sheet metal fabrication and enclosures
  • Automotive body and panel work
  • Kitchen equipment and stainless steel fabrication
  • Signage and display mounting
  • Architectural and construction cladding
  • Electrical cabinet and switchboard assembly
  • HVAC ductwork and insulation pin fixing

Why Choose CD Studs?

Capacitor discharge stud welding is a fast, efficient, and cost-effective method for attaching threaded fasteners to metal surfaces without damaging the opposite face. Unlike traditional welding or drilling methods, CD stud welding with mild steel studs like these M4 x 30mm units provides a strong mechanical bond in a fraction of a second, reducing labor time and increasing productivity on the workshop floor.
