The PHM metric weld pin has three identical precision projections on the underside
of the head permitting the pin to be used on through-hole applications. These projections
also permit exact positioning and balance for optimum welds. In through-hole applications,
the head of the pin is welded to the component's metal making a joint stronger then
the surrounding area. This great strength makes the PHM weld pin ideal for hinge
pins, bearing surfaces, structural supports and stops.
