Description

BaerCoil Thread Insert Metric - M20 x 2.5 is a high-performance reinforcement solution designed for damaged or high-load threaded holes. Built for engineers and technicians, it delivers reliable, long-lasting thread integrity in demanding environments.

  • Material: Austenitic chromium-nickel stainless steel (AISI 304) with a minimum tensile strength of 1400 N/mm² for superior durability and corrosion resistance.
  • Cross-section & manufacturing: Cold-formed swaging creates a rhombic cross-section, optimizing thread engagement and allowing maximum use of available space inside the hole.
  • Size: Metric insert compatible with M20 x 2.5 threads, providing precise, reusable leverage for standard fasteners.
  • Wear and heat resistance: Enhanced wear resistance and better surface finish reduce thread abrasion and performance degradation under high temperatures.
  • Corrosion resistance: Stainless steel construction offers robust protection against moisture and corrosive environments, extending service life.
  • Installation reliability: Designed to lock securely into the host material, delivering a stable, durable thread in a single-screw connection without sacrificing performance over time.

BaerCoil inserts deliver a durable, repeatable thread that supports higher torque, better fatigue resistance, and longer service life compared with standard threaded holes. Ideal for repairs, reinforcements, or retrofits in machinery, automotive, hydraulic, and industrial equipment, this M20 x 2.5 insert distributes stress efficiently and minimizes pull-out risk thanks to its rhombic geometry. Choose BaerCoil for a trusted, long-lasting solution when thread longevity matters.
