Stainless steel 1d 1.5d 2d 2.5d wire thread inserts with preformed notch
Helically coiled threaded inserts deliver superior, permanent, and wear-resistant internal threads, simplifying installation into molded or drilled holes in just one step, offering unparalleled reliability.
Helically coiled wire thread inserts are ingeniously coiled fastenings, ideal for reinforcing threads and safeguarding tapped holes against potential failure. Each insert distributes the load evenly over the entire bolt and hole, drastically improving holding capacity and resistance to pull-out forces. Our thread inserts are manufactured from premium 304 stainless steel wire, expertly rolled into a resilient diamond-shaped cross-section for optimal performance.
