Learn more about Klarna
Description
BaerCoil UNC 7/8 x 9 - 3XD is a high-strength stainless steel thread insert designed to reinforce and extend the life of threaded joints in demanding machinery and equipment. Built for reliability, it delivers superior wear, corrosion, and heat resistance in a compact, space-efficient form.
- Material: Austenitic chromium-nickel stainless steel (AISI 304) with tensile strength at least 1400 N/mm2
- Cross-section & Manufacturing: Wire swaged in cold-form to a rhombic cross-section for maximum thread engagement and efficient use of space
- Size & Depth: UNC 7/8" x 9" thread insert, with a recommended installation depth of 3XD
- Performance: Superior wear resistance, reduced thread abrasion, improved surface finish, and enhanced corrosion and heat resistance vs. standard connections
- Finish: Natural stainless-steel finish designed for durability in tough environments
By reinforcing the host thread, this BaerCoil insert extends service life in high-cycle or high-load applications, minimizes the risk of thread stripping, and maintains secure torque transmission even under demanding conditions. The rhombic cross-section distributes load evenly, helping preserve hole integrity over time. Ideal for maintenance teams and OEMs seeking reliable, long-lasting fastener performance with consistent results.
