BaerCoil's metric thread insert for M12 x 1.75 threads delivers a durable, high-precision joining solution designed for repeatable, long-lasting performance in metal assemblies. Built for engineers, machinists, and assembly professionals, it provides reliable thread life in demanding environments.

  • Size & Thread: M12 x 1.75 metric thread; length is 2.5 × D (approximately 30 mm), suitable for standard M12 holes
  • Material: Austenitic chromium-nickel steel (stainless steel AISI 304) with a tensile strength of at least 1400 N/mm2
  • Cross‑Section: Rhombic profile achieved by cold-form swaging for maximum load transfer and efficient space use
  • Manufacturing: Cold-form swaging ensures consistent geometry and strong thread engagement
  • Performance Advantage: Enhanced wear resistance, reduced thread abrasion, improved surface finish, and superior corrosion and heat resistance compared with typical single-screw connections

These inserts distribute load more evenly across the tapped hole, resist loosening under vibration, and extend the service life of threaded joints. The rhombic cross‑section and stainless steel construction provide enduring strength in mechanical, automotive, and industrial applications, making maintenance easier and downtime shorter.
