Galvanized Rigging Screw No. 401

No. 401 Rigging Screws

Ultra-High Strength Rigging Hardware

Our No. 401 Style Rigging Screws, also known as bottle screws, are designed for the most demanding tensioning tasks in the maritime and structural engineering sectors. Featuring an enclosed pipe body, these screws protect the internal threads from dirt, moisture, and impact, ensuring smooth operational life in Dubai's desert and coastal environments.

The Jaw & Jaw configuration provides a permanent, non-detachable connection to anchor points and eyes, essential for ship's rigging, permanent structural tensioning, and heavy industrial plant maintenance. Coated with hot-dip galvanization, they offer unparalleled protection against corrosion and oxidation.

  • Material: Forged Carbon Steel / Pipe Body
  • Security: Double Jaw (Clevis) ends with high-tensile security pins
  • Protection: Enclosed body to preserve thread integrity
  • Applications: Ship's stays, industrial machinery securing, and high-tension structural rigging
