BaerCoil UNC thread insert No4 x 40 - 2.5 × D is a high‑strength stainless steel solution engineered to reinforce and repair threaded holes in metal assemblies. Crafted from austenitic chromium-nickel steel (AISI 304) with a tensile strength of at least 1400 N/mm2, it delivers dependable performance in demanding environments.

  • Material: Austenitic chromium-nickel stainless steel (AISI 304) with minimum tensile strength ≥ 1400 N/mm2.
  • Cross‑Section: Rhombic profile produced by cold‑form swaging for optimized load distribution and maximum space utilization.
  • No4 x 40 size: UNC thread insert designed for standard UNC tapped holes; length adheres to the 2.5 × D guideline for strong engagement.
  • Corrosion & Heat Resistance: Stainless steel construction provides superior resistance to corrosion and elevated temperatures.
  • Wear & Abrasion Resistance: Enhanced wear resistance and reduced thread abrasion compared with conventional single-screw connections.

Designed for durability across a range of industrial applications, the BaerCoil UNC No4 x 40 delivers reliable, long‑lasting threads even in challenging service conditions. The rhombic, cold‑formed geometry improves thread engagement and load transfer, helping prevent thread pull‑out, while the stainless steel composition guards against corrosion and heat‑related degradation. Whether repairing damaged threads or reinforcing existing ones, this insert offers a robust fastening solution that supports maintenance efficiency and extended component life.
