CD Threaded Collar Weld Stud Features

CD Threaded Collar Weld Studs combine a threaded fastening point with an integrated collar that acts as a spacer, helping maintain consistent separation between the welded surface and mounted components.

Integrated Collar

The built-in collar creates a fixed stand-off between the base metal and the attached part, eliminating the need for separate spacer components.

Threaded Mount

The threaded section provides a permanent fastening point for components requiring secure mechanical attachment after welding.

Spacer Function

CDC weld studs maintain consistent spacing across assembled parts, helping simplify installation and improve assembly repeatability.

Material Choices

Available in mild steel and stainless steel, these weld studs accommodate different fabrication and application requirements.

Standard B Collets

Standard 1-3/8" long B collets are listed for tool setups, but note that they may require a B Stop.

Accessory Fit
