CD PIN ANNEALED .105 X 1 1/4 -1000/PKT

CD Pin Weld Studs – Annealed, .105" x 1-1/4" (1000/Pkt)

Premium Capacitor Discharge (CD) Annealed Weld Pins for Insulation & Fastening Applications

Engineered for precision and reliability, these .105" x 1-1/4" annealed CD weld pins are the ideal choice for capacitor discharge (CD) stud welding applications requiring fast, clean, single-sided welds without back-marking or distortion. Each package contains 1,000 pins, making it a cost-effective bulk solution for contractors, fabricators, insulation installers, and industrial manufacturers.

Key Features

• Diameter: .105" (2.7mm) — ideal for lightweight to medium-duty fastening
• Length: 1-1/4" (31.75mm)
• Material Condition: Annealed — softened through heat treatment for improved ductility, easier bending, and reduced brittleness
• Weld Process: Capacitor Discharge (CD) stud welding — no flux, no back marking, instant bonding
• Packaging: 1,000 pins per packet (PKT) for high-volume jobs
• Finish: Clean, burr-free tip for consistent arc initiation and weld quality

Common Applications

• Securing insulation to metal ductwork, tanks, and vessels
• HVAC and sheet metal fabrication
• Attaching insulation pins/washers in commercial and industrial buildings
• Shipbuilding and marine insulation retention
• Automotive and appliance manufacturing
• General metal fastening where a smooth, unmarked reverse surface is required

Why Choose CD Annealed Weld Pins?

Capacitor discharge welding delivers a rapid, low-heat weld that fuses the pin to the base metal in milliseconds — minimizing thermal distortion on thin gauge materials. The annealed finish makes these pins easier to bend or crimp after welding (commonly used with speed clips or insulation washers), without cracking or snapping, which is critical for insulation retention applications.

Compatibility

Designed for use with standard CD stud welding guns and equipment. Ensure your welder is calibrated for .105" diameter pins for optimal weld penetration and holding strength.
