CD Threaded Flanged Weld Studs are precision fastening components engineered for Capacitor Discharge stud welding on thin sheet metal. Their controlled weld characteristics allow secure threaded attachment while producing little to no reverse-side marking when properly installed.
Designed for manufacturing environments requiring consistent cosmetic appearance and reliable fastening performance, these studs are available in multiple thread sizes and are supported by a complete range of compatible collets, inserts, and accessories.
Manufactured for precision fastening, CD weld studs combine threaded performance with controlled weld characteristics for cosmetic sheet metal applications and light structural assemblies.
The Capacitor Discharge welding process concentrates weld energy in a very short cycle, allowing CD welding studs to be installed with little to no reverse-side marking on properly selected sheet metal.
The integral flange distributes clamping force across a larger contact area, improving load transfer while helping protect thinner materials during assembly.
Although optimized for CD stud welding installation, these studs can also be welded using the ARC Short Cycle process when application requirements and material thickness permit.
Available in thread sizes from 4-40 through 3/8-16, supporting electrical enclosures, HVAC equipment, appliance manufacturing, transportation components, and fabricated sheet metal products.
Designed for use with Standard B, Short B, Long, and EURO collets, together with dedicated collet inserts selected according to stud length for accurate positioning during welding.
Manufactured in mild steel and aluminum to satisfy a variety of fabrication environments while maintaining consistent CD weld stud specifications for repeatable installation.
Selecting the proper CD weld studs, collets, inserts, and stops ensures consistent welding performance and minimizes setup time on the production floor. Our technical team can help match every component to your stud size, welding equipment, and manufacturing requirements.
