Learn more about Klarna
Description
BaerCoil UNC thread insert, 5/16-18 with a 1.5D length, provides durable internal thread reinforcement for demanding assemblies. Crafted from austenitic chromium-nickel stainless steel (AISI 304) with high tensile strength, it delivers reliable performance in challenging environments.
- Material: Austenitic stainless steel (AISI 304) with a tensile strength of at least 1400 N/mm2 for strong, long-lasting threads.
- Cross-Section: Rhombic profile achieved through cold-form swaging, maximizing thread engagement and efficient use of space.
- Size and Length: UNC 5/16-18 thread, length 1.5 times the nominal diameter (1.5D) for deeper, more secure engagement.
- Wear and Corrosion Resistance: Designed to improve wear resistance, reduce thread abrasion, and enhance surface finish and corrosion resistance over standard connections.
- Manufacturing Process: Precisely swaged from wire via cold-forming to ensure consistent geometry and performance across each insert.
- Application: Ideal for reinforcing or repairing internal threads in tapped holes where a durable, high-performance connection is required.
BaerCoil inserts deliver a secure, durable thread connection that resists wear, corrosion, and heat over time. The rhombic geometry maximizes contact area for better load distribution, reducing the risk of strip-out in high-cycle or vibration-prone applications. With these inserts, you gain a reliable fastening solution that extends service life, improves surface finish, and supports consistent assembly quality across maintenance and production environments.
