Increase spinout resistance with our specially designed insert featuring knurls under the head. Suitable for varying thicknesses over .062â€/1.57 mm, including blind applications, it offers reliable performance in restricted space scenarios with minimal backside protrusion. Available in multiple thread sizes and grip ranges, this insert is not your typical stock item. Crafted from low carbon steel and finished with cadmium plating, it ensures durability and corrosion resistance. Please note that the internal threads are intentionally oversized to accommodate shrinkage during installation, ensuring compatibility with Class 2A/3A or 6g screws post-installation. Additional materials are also available for customization.
