The BT weld bracket, with its dual-line projections, provides a threaded hole at a right angle to the component to which it is welded. The BT is welded without drilling or punching a hole because it is attached to and not through the surface. The dual-line projections contain the right amount of metal, are uniform in height and length to assure a sound permanent offset thread to which the mating parts can be quickly and firmly attached.

In the larger thread sizes, there is a pilot that insures the proper thread engagement.
