Intended for through-hole applications, the HWM weld screw, with its three projections located precisely under the head, permits flush mounting. The projections are of the exact height, diameter and mass to assure the proper positioning and balance for optimum welds. Through-hole use allows self-locating and eliminates the need for fixturing.
