Learn more about Klarna
Description
BaerCoil UNC thread insert for 3/8-16 is a stainless steel repair solution designed to restore durable, wear‑resistant internal threads in damaged or soft metal components. Built for engineers, machinists, and maintenance professionals, it delivers reliable performance in demanding assemblies where thread integrity matters.
- Material: Austenitic chromium-nickel stainless steel (AISI 304) with a tensile strength of at least 1400 N/mm2 for strong, long‑lasting threads.
- Cross-Section: Rhombic profile achieved by cold‑form swaging, enhancing load distribution and maximizing thread engagement within the host material.
- Thread Size: UNC 3/8-16 internal thread standard, compatible with common fasteners and hardware.
- Installation Depth: 3 × D length designation provides robust engagement and improved resistance to pull‑out under load.
- Corrosion & Wear Resistance: Stainless steel construction offers superior wear resistance and corrosion tolerance in challenging environments.
When you install a BaerCoil thread insert, you get a reusable, high‑strength thread that helps prevent thread stripping and extends the life of components. The combination of a rhombic cross‑section and durable stainless steel delivers better wear performance, smoother surface finish, and more consistent torque characteristics across cycles. This makes it an ideal choice for maintenance and repair in machinery, automotive parts, and equipment exposed to moisture, heat, or chemicals, where lasting thread integrity is crucial and downtime is costly.
