Abstract: A weld nut assembly, including: an annular flange structure; and an annular body structure coupled to the annular flange structure; wherein the annular flange structure and the annular body structure collectively define an inner bore, wherein at least a portion of the inner bore defined proximate the annular flange structure defines threads adapted to receive a screw disposed within the inner bore. The weld nut assembly further includes an annular washer or bottom structure coupled to the annular flange structure. Optionally, the weld nut assembly further includes an annular ring projection and a plurality of circumferential weld protrusions coupled to the annular flange structure. The annular flange structure is adapted to be welded to a surface of a body panel or other structure of a vehicle with the inner bore aligned with a hole formed through the body panel or other structure, the hole adapted to receive the screw therethrough.

Abstract: A handheld quality inspection tool for projection welded components and method for utilizing the same is disclosed. The handheld quality inspection tool includes an elongated hollow tube, a spring support, a spring member, a plunger, and a handle. The elongated hollow tube defines a slot. The spring support is connected to an end portion of the elongated tube. The spring member is disposed within the elongated hollow tube and connected to the spring support. The plunger is disposed in the elongated hollow tube and connected to the spring member opposite the spring support. The handle is connected to the plunger and protrudes from the elongated hollow tube through the slot and is translatable along the slot to move the plunger and compress the spring member. Upon release of the handle, the compressed spring member propels the plunger to apply an impact force to a projection welded component.
