Full Product Description
CD Studs (Capacitor Discharge Studs) are a fast, clean, and highly reliable method of attaching threaded fixing points to thin-gauge sheet metal without distortion, discoloration, or damage to the reverse (visible) surface. This listing is for a stainless steel, internally threaded stud measuring 4mm ID (M4 thread) x 20mm in length, supplied in a bulk pack of 100 pieces — ideal for tradespeople, fabricators, and manufacturers needing a reliable stock supply.
Manufactured from high-grade stainless steel, these studs offer excellent corrosion resistance, making them suitable for indoor and outdoor applications, food-grade environments, and areas exposed to moisture or washdown conditions.

Why Choose CD Weld Studs?
Unlike drilled and tapped holes, CD studs are welded in milliseconds using a capacitor discharge welding gun, fusing the stud to the base metal with minimal heat input. This means no warping, no blow-through, and no visible marking on the finished (front) side of thin stainless steel sheet — a critical requirement for high-quality, presentation-grade fabrication work.
