Description

BaerCoil BA thread inserts are precision-engineered fasteners designed to reinforce and extend the life of threaded joints in metal assemblies. Crafted from corrosion-resistant stainless steel and formed into a compact rhombic profile, they deliver reliable, long-lasting performance in demanding environments.

  • Material: AISI 304 stainless steel (austenitic chromium-nickel) with a tensile strength of at least 1400 N/mm2.
  • Cross-Section: Rhombic profile achieved through cold-form swaging for maximum engagement and efficient use of space.
  • Size/Diameter: BA 4 with a length of 2.5 x D, optimized for strong thread formation in restricted spaces.
  • Manufacturing Process: Cold-work swaging that enhances thread grip and load distribution across the insert.
  • Performance: Superior wear resistance, reduced thread abrasion, and improved surface finish compared with standard screw connections.
  • Durability in Harsh Environments: Enhanced corrosion resistance and heat tolerance for reliability in challenging conditions.

BaerCoil BA thread inserts deliver a durable, vibration-resistant interface that helps maintain thread integrity, even under repeated assembly and disassembly. The combination of stainless steel composition, rhombic cross-section, and precise cold-form manufacturing translates into a secure, long-lasting connection that improves overall assembly reliability.
