BaerCoil UNC thread insert (9/16-12, 2.5D) is a high-strength fastener solution designed to deliver durable, vibration-tolerant threads in metal assemblies. Built from stainless steel AISI 304, it combines corrosion resistance with impressive load-bearing capability for demanding applications.

  • Material and strength: Austenitic chromium-nickel stainless steel (AISI 304) with a tensile strength of at least 1400 N/mm2 for reliable performance in tough environments.
  • Profile and formation: Rhombic cross-section achieved through cold-form swaging, optimizing load distribution and maximizing space utilization in threaded joints.
  • Thread compatibility: Designed for UNC standard threads (9/16-12) to match common, heavy-duty fasteners and maintain common assembly workflows.
  • Length and engagement: 2.5 times the nominal diameter (2.5D) grip/engagement length for strong withdrawal resistance without compromising fit in tight spaces.
  • Corrosion and heat resistance: Stainless steel core provides robust resistance to corrosion and elevated temperatures, extending service life in harsh or outdoor environments.
  • Wear and surface finish: Enhanced wear resistance and improved surface finish compared with traditional single-screw connections, helping maintain thread integrity over time.

This BaerCoil insert is ideal for applications where long-term thread integrity matters: automotive housings, machinery frames, equipment enclosures, aerospace components, and any project facing vibration, repeated assembly cycles, or exposure to challenging conditions. The rhombic, cold-formed geometry ensures efficient use of space while delivering predictable performance, making it a practical upgrade over standard threaded connections. Installation benefits come from the solid stainless core and proven BaerCoil profile, supporting reliable, repeatable results across maintenance or production environments.
