The square-bodied, through-hole SF weld nut features a 3600 ring weld projection. This ring projection gives a hermetic seal and is particularly adaptable to welding to cross wire. The greater weld area is advantageous when welding to thin-gage material because it provides extra strength to resist torque and shearing. An additional advantage of this nut is that it can be welded to cylindrical surfaces.

A thicker wall and the rugged construction of the SF weld nut makes it ideal for extra heavy-duty applications requiring greater strength and rigidity.
