Simpson Strong‑Drive SDS 1/4 in. x 3-1/2 in. heavy‑duty connector screw (model family SDS25312) — a 1/4"‑diameter structural screw engineered for connector, wood‑to‑wood and engineered wood connections. Typical catalog features include a Type‑17 self‑drilling point for fast installation, integrated washer for bearing at connector heads, and a stamped head for easy post‑install identification. The screw is offered in corrosion‑resistant finishes (double‑barrier coated variants and Type‑316 stainless steel) and common trade pack sizes (10, 25, 125, bulk 900, etc.). Simpson recommends installation with a low‑speed 1/2" drill and a 3/8" hex driver. Based on current retail listings I sampled (see sources), a competitive local resale recommendation for a single unit in Dayton, IA (zip 50530) is about $1.10 each (see price breakdown in priceOffers).
