The weld screw is designed with a long, narrow spade at right angles to the thread and a single button weld projection. The weld screw is particularly suitable for use in narrow channels, confined areas and corners. It can also be used in applications where threads must be offset from the surface. The weld screw is easy to locate and it produces a strong, sound weld. ProductSiteLaunchDate : 2018-03-28T07:00:00.000Z Size : 5/16-18 UnitCount : 1 UnspscCode : 31161500
