Introduction:
1.The screw threads being locked by polygonal deformation of one or more turns of the thread.
2.This deformation results in a powerful locking on rhe sides of the screw thread and counteracts the unscrewing effects of dynamic stress,vibrations and thermal loads.
3.Colour:Red;stainless steel true colors.
Features:
Wear resistance
Corrosion resistance
Heat resistance
Material saving
Can be customized if necessary
Provide a durable threaded hole in a soft material
Eliminating a machining operation
