Complete Stud Welding

No Thread W/ Hole Weld Studs

No Thread W/ Hole Weld Studs are ARC weld studs designed for insulation fastening applications where retention wire is used instead of threaded hardware. Each stud is manufactured with a precision-drilled cross hole that allows wire to pass through after welding, securely holding blanket insulation against the base material.

Complete Stud Welding supplies No Thread W/ Hole Weld Studs in mild steel and stainless steel for industrial furnaces, ductwork, tanks, process equipment, and thermal insulation systems. Multiple diameters are available with drilled cross-hole configurations to meet application requirements.

  • Drilled Cross-Hole for Wire and Cotter Pin Lacing
  • Unthreaded Smooth-Shank High-Speed Loading Design
  • Direct One-Sided Drawn Arc Structural Bonding
  • Available in Low-Carbon Mild Steel & Stainless Steel

No Thread W/ Hole Weld Stud Features

Engineered for intense thermal expansion and industrial vibrations within boilers and exhaust systems, these cross-drilled No Thread W/ Hole Weld Stud fasteners deliver definitive mechanical insulation anchoring over long lifecycles.

Lacing Hole Geometry

The tip features a cleanly machined cross-hole (0.156" or 0.188") at a 0.500" threshold. This channel permits rapid threading of tie wires, eliminating secondary capping hardware.

Threadless Shank Profile

The smooth, unthreaded outer body prevents thread fouling or slag contamination in rugged field environments. It ensures swift, clean impalement of fiber blankets without binding.

Single-Sided Metallurgical Fusion

Utilizing standard drawn arc welding systems, No Thread W/ Hole Weld Stud fasteners execute an instantaneous, full-cross-section weld. This creates a penetration zone stronger than the base metal without backside access.

Arc Flash Containment

Paired with diameter-specific ceramic ferrules (F037-F/F050-F), the molten pool is perfectly molded. This builds a consistent base fillet weld up to 0.688" wide for structural stability.

Shop Floor Integration

The No Thread W/ Hole Weld Stud series drops effortlessly into automated or manual production lines. The 0.375" and 0.500" bases map perfectly to standard GN grips and CN chucks to maximize system uptime.

Flexible Material Selection

Manufactured in mild steel and stainless steel, these weld studs can be selected as per service conditions, environmental exposure, and project specifications.
