Description

BaerCoil UNF thread inserts in the 5/8-18 size with a 1.5xD length provide a durable, high-strength solution for reinforcing and repairing threaded holes in metal components. Built for professionals who demand reliable performance in demanding environments, this insert delivers secure, long-lasting thread engagement.

  • Thread size: UNF 5/8-18 for standard high-torque applications
  • Length: 1.5 × D, optimized for strong engagement in through-holes
  • Material: Austenitic chromium-nickel stainless steel (AISI 304), with tensile strength of at least 1400 N/mm2
  • Cross-section: Rhombic profile achieved by cold-form swaging for efficient load distribution and maximum use of available space
  • Corrosion resistance: Stainless steel construction provides superior protection in moisture and harsh environments
  • Wear and heat resistance: Designed to resist thread abrasion and maintain performance under repeated assembly and disassembly
  • Manufacturing quality: Precision-swaged inserts that promote consistent torque-tension behavior and long service life

BaerCoil thread inserts improve thread connections by combining a robust stainless-steel composition with a geometry that distributes load effectively while occupying minimal space. The result is a more durable boss for fasteners, reduced risk of thread stripping, and a smoother surface finish that supports cleaner assembly and disassembly in demanding applications.
