Description
BaerCoil UNF thread insert for 3/8-24 provides a durable, repairable threaded solution designed for high-demand assemblies. Built from stainless steel AISI 304 with a minimum tensile strength of 1400 N/mm2, it’s ideal for engineers and technicians seeking lasting thread integrity in metal components, with a grip length of 2.5 times the diameter.
- Size and thread: UNF internal thread 3/8-24 for precise, high-torque connections.
- Material: Austenitic chromium-nickel stainless steel (AISI 304) offering strong corrosion resistance and durability.
- Cross-section: Rhombic profile created by cold-form swaging to maximize engagement and minimize play.
- Manufacturing method: Cold-form swaging ensures consistent geometry and efficient use of space within the assembly.
- Wear and corrosion resistance: Enhanced wear resistance and surface finish reduce thread abrasion and extend service life in demanding environments.
- Heat resistance: Robust performance under elevated temperatures helps maintain thread integrity across thermal cycles.
These inserts strengthen threads in softer base metals, resist damage from repeated assembly and disassembly, and help sustain reliable torque and clamping force. The combination of austenitic stainless steel and the rhombic, swaged design delivers a durable, high-performance solution that improves longevity, reduces maintenance downtime, and supports precision assemblies where thread wear and corrosion are concerns.
