Standard Insertable Stock Flanges
Fixed Length with Welded Flanges
Screws that attach directly to existing bases or mounting plates using welded flanges.
Models 1, 5, 8
Welded ground screws are ideal for structures or building products with existing bases or mounting plates. One-piece ground screws attach directly to the structure for a solid foundation with fewer steps. Welded flanges come in three varieties — Models 1, 5 and 8 — which offer different attachment formats and flexibility.
