CD Threaded Non Flanged Weld Studs

CD Threaded Non Flanged Weld Studs are designed for applications where a low-profile welded fastening point is required without a traditional flange base. These CD weld studs provide a compact attachment solution for sheet metal assemblies where clearance, hole size, and surface appearance are critical considerations.

Manufactured for the Capacitor Discharge (CD) stud welding process, these welding studs create a secure weld connection with minimal heat transfer and little to no reverse-side marking. Complete Stud Welding supplies compatible collets and accessories to support accurate installation across different thread sizes and application requirements.

  • Non-Flanged Design for Reduced Component Clearance
  • Zero Backside Thermal Discoloration
  • Compatible With Capacitor Discharge Stud Welding
  • Minimal Heat Impact on Thin Sheet Materials

Product Overview

CD Threaded Non Flanged Weld Studs provide a compact fastening solution for sheet metal applications where minimizing the mounting footprint is important. Their non-flanged construction allows installation in tighter spaces while maintaining a reliable threaded attachment point.

Designed for Capacitor Discharge stud welding, these weld studs are available in multiple thread sizes and are supported by a complete range of compatible collets, inserts, and accessories for repeatable installation performance.

CD Threaded Non Flanged Weld Stud Features

CD Threaded Non Flanged Weld Studs provide a streamlined fastening option for assemblies requiring a welded threaded connection with minimal base profile. Their compact construction makes them suitable for precision sheet metal applications where standard flanged studs may not fit.

Low-Profile Stud Geometry

The non-flanged design eliminates the larger flange footprint found on traditional weld studs. This allows components to be mounted with reduced clearance requirements while maintaining a dependable welded connection.

B Collet Hardware Stop Rules

Standard 1-3/8" long B collets and short 1-3/16" long B collets are typically used to hold the studs. Both of these options require a matching B Stop to function correctly.

Extended Collet and Insert Matching

For alternative production setups, long 2-3/8" collets can be used alongside dedicated Long Style Stops. When using 1-3/4" collet inserts, the inserts must be selected based on the specific length of the stud.

Thin Sheet Metal Application Support

Designed for applications requiring limited heat exposure, these CD weld studs can be installed with little to no reverse-side marking. This makes them suitable for finished panels, enclosures, and fabricated sheet metal components.

Threaded Attachment Capability

The threaded configuration provides a permanent fastening point for mounted components, eliminating the need for separate nuts, drilled holes, or additional hardware installation steps.

Flexible Size and Accessory Selection

Available thread sizes from 4-40 through 3/8-16 provide options for different fastening loads and assembly requirements. Matching collets and inserts help maintain proper stud alignment during welding.
