ruthex Threaded Insert #4-40 UNC (100 pieces), #4-40x5,7

These ruthex thread inserts are made of high-quality brass and are first-class processed thanks to low production speeds. They have opposing spiral knurled nuts that guarantee an extra firm hold. When installed, the threaded inserts therefore offer incredible tensile force as well as high tightening and loosening torque.

Using ruthex thread inserts is easier than ever: insert using heat or ultrasound and enjoy stable threads for 3D applications! The high-quality brass ensures high corrosion resistance and thermal conductivity.

Tip: The high-quality thread inserts can be used several times without the risk of them tearing out. After they are no longer needed, they can be carefully removed.
