BaerCoil M42 x 3.0 thread inserts are precision stainless-steel inserts designed to reinforce threads and extend the life of threaded joints in demanding assemblies. Crafted from austenitic chromium-nickel steel (AISI 304) with a tensile strength of at least 1400 N/mm2, these inserts are built to perform in challenging environments.

• Size and fit: Metric M42 x 3.0 thread with an insertion length of 1.5 × D, delivering a balanced combination of strength and reliable seating.
• Material: AISI 304 stainless steel (austenitic chromium-nickel) for excellent corrosion resistance and durability in varying conditions.
• Cross-section: Wire is swaged in cold-form to a rhombic cross-section, maximizing thread engagement and space utilization inside the hole.
• Performance: Enhanced wear resistance, reduced thread abrasion, smoother surface finish, and improved heat and corrosion resistance compared with standard single-screw connections.
• Manufacturing approach: Cold-form swaging creates a tight, precision-fit insert that supports consistent torque and long service life.

These inserts are ideal for applications requiring strong, reusable threads in metal components—where vibration, thermal cycling, or frequent disassembly can degrade ordinary threads. Use cases include robust enclosures, machinery housings, and other precision assemblies that demand durable, reliable threaded connections with long-term performance.
