Weld Nuts

Advance stocks four styles of Weld Nuts manufactured by Buckeye Fasteners: Steel piloted square 4-projection weld nuts (WP); hex piloted 3-projection weld nuts (HS); single-tab spotweld nuts (SN); and double-tab spotweld nuts (ND).

WP weld nuts have a square piloted projection and are designed for use in through-hole applications. A precision pilot facilitates feeding by locating quickly and positively in the sheet hole. Rounded corners ease use in confined areas and the four projections provide proper seating and strong welds. Long a favorite of automotive and farm equipment manufacturers, the square, piloted weld nut has four large weld projections to ensure a strong, reliable weld every time. The countersunk locating pilot guides the mating part into the threaded hole. Available in various pilot heights so it can be welded to a wide range of metal thicknesses.

HS weld nuts have three uniform projections that ensure reliable contact with the weld surface, even if it is not perfectly flat. The precision pilot accurately locates the threads in the pilot hole and prevents the nut from slipping off center during welding.

The SN weld nut (economy t-nut) is a spot weld, precision-pilot nut which features an optimum welding tab. The tab will take several sizes of electrodes, and permits use of the same equipment, settings and electrodes used to produce your product or product components. If needed, the SN weld nut is designed to function as a stiffener or brace, and can be also be used as a fastener.

The ND weld nut is a dual-tab spot weld nut for applications requiring additional strength where tension is against the weld. It is the standard slot fastener in the aluminum extrusion industry (economy t-nut). The location of the twin-tabs enables the ND weld nut to be used in bridging corners and recessed areas. A precision pilot speeds location and provides a full thread engagement. The ND weld nut can use the same electrodes, equipment and settings used in production, thus eliminating setup and changeover time, thereby lowering costs and time.
