Weld Stud with 3 Projections Under the Head

This Projection Weld Screw features three precision weld projections located underneath the head. This design allows for flush mounting of the weld screw onto its designated surface. The three projections are of equal height, diameter, and mass to facilitate a properly balanced and positioned weld. This weld screw is designed for through-hole applications, is self-locating, and eliminates the need for additional fixturing. These industrial fasteners are available from Monroe-JHP Fasteners in a variety of materials, dimensions and thread sizes (inch and metric).

Application notes

This projection weld screw is self-locating and provides a flush surface for easy attachment of mated components. Three symmetrical weld projections located underneath the head allow for a robust weld that will be properly positioned and well balanced. No special tooling or fixturing is required.

For applications that require a flush-mounted, through-hole, weld screw that can be easily coupled with a mated component, this projection weld screw will get the job done. Its sturdy design ensures that resulting welds will be strong, balanced, and durable.
