The RWM weld screw, for through-hole applications, features a 360 degree ring projection that provides a circular weld seal. The large weld area on the RWM gives great weld strength which can be used in applications requiring additional weld strength. The full ring projection is also ideal for cross wire welding or welding to screen, perforated metal or tubing. The RWM weld screw is found on applications in the air conditioning and refrigeration industry.
