Description

Restore damaged internal threads quickly and reliably with the VCOIL UNC Thread Repair Workshop Kit. Perfect for maintenance, installation, and small-batch production, it combines durable stainless inserts with a compact case for fast, cost-effective repairs.

  • UNC Thread Range: Internal thread repair kit covering common UNC sizes from 1/4" to 1/2" to match standard fasteners.
  • DIN 8140 Stainless Steel Inserts: Wire thread inserts crafted from durable stainless steel, aligned to DIN 8140 with ISO 2 tolerance (6H) for a precise, long-lasting fit. Type S offers smooth, free-running threads.
  • Thread Armour Plating: Specialized plating designed for materials with low shear strength, enhancing grip and extending the life of repaired threads.
  • All-in-One Case: Curated assortment of the most popular dimensions stored in a compact, organized case for quick access and neat storage.
  • Recovery Capability: Enables restoration of rejected or worn components, delivering a cost-effective solution and reducing waste.
  • Durable Construction: High-stability, long-lasting internal threads designed for maintenance, installation, and small-series production.

Reclaim worn or damaged threads without replacing parts, cutting downtime and material waste. The kit’s stainless-steel inserts, DIN 8140 standard alignment, and ISO 2 6H tolerance deliver reliable, repeatable repairs for UNC fasteners, while Thread Armour Plating protects soft substrates. The organized case keeps popular sizes readily available, making maintenance, installations, and small production runs faster and more efficient.
