Typically used as a ground attachment point in electrical control cabinets, computer consoles, transformer frames or on any metal fabrication where a common ground (earth) attachment point is required. The studs are available in two distinct styles.... 1) As a standard 1/4" push on type connector or 2) As a threaded type with an enlarged weld base providing a large upper contact area for attachment of lugs. Both types can be welded with standard CD stud welding equipment. The push on style can be welded with the Cutlass Classic, Clipper 8 or 10, or equivalent. The threaded type requires a Clipper 10 or equivalent CD stud welder.
