Nelson Fastener Systems Unthreaded Stored Arc®Stud ANC / ANS / ANA

Nelson ANC, ANS and ANA unthreaded studs are designed to be welded to thin gauge sheet metal using the Stored-Arc method of stud welding, or a transformer/rectifier power-control source in the short-cycle mode. These applications generally provide a weld bond that is greater than the strength of the sheet to which they are welded.Nelson Stored Arc studs have a flanged weld base that is about 1/32”, or 1mm, greater than the nominal stud diameter.

The “A” flange allows automatic stud feeding for increased production speeds. The flange also increases the stress area on the sheet.Standard studs come in lengths up to 1.25”. Unthreaded Stored Arc studs are commonly used as locator or stop points. They may also be tapped with internal threads, or have smaller diameter externally threadedextensions Mild steel studs are copper flash plated, stainless studs are passivated, and aluminum studs are acid etched for superior weld results.

Nelson Stored Arc studs have a flanged weld base that is 1 mm greater than the nominal stud diameter. The “A” flange allows automatic stud feeding for increased production speeds. The flange also increases the stress area on the sheet. Standard studs come in lengths up to 30mm. Unthreaded Stored Arc studs are commonly used as locator or stop points. They may also be tapped with internal threads, or have smaller diameter externally threaded extensions. They also may have Speed Clips or self-threading nuts installed on them, and can be made with special chamfers to aid in the installation of such clips or nuts. Mild steel studs are copper flash plated, stainless studs are passivated, and aluminum studs are acid etched to assure superior weld results
