Engineered for Ultimate Structural Security: Open Wedge Sockets with Bolt & Nut

The Open Wedge Socket with Bolt and Nut (OWS-B) is a highly versatile wire rope termination solution designed for critical rigging and lifting applications requiring enhanced connection security. Manufactured from quenched and tempered cast steel, these sockets utilize a wedge-style clamping mechanism combined with a heavy-duty bolt and nut fastening system to prevent unintended pin release, ensuring maximum structural integrity in demanding industrial environments.

Maximum Strength & Material Safety
  • Premium Casting: Manufactured from high-grade quenched and tempered cast steel to provide superior durability and fatigue resistance under high load cycles.
  • Certified Load Capacities: Standard models feature a Minimum Breaking Load (MBL) ranging from 9 UStons up to 689 UStons.
  • Traceable Quality: Every socket is supplied with an EN 10204-2.1 declaration of conformity and an EN 10204-3.1 material certificate.

  • Corrosion Protection: Finished with a standard blue primer coating and hot-dipped galvanizing (Note: OWS 0.25 and 0.5 models are galvanized only).

Precision Engineering & Field Versatility
  • Broad Wire Compatibility: Optimized to accommodate wire rope diameters from 5/16″ up to 3″ (specialized models for 3-3/4″).
  • Enhanced Security: Features a bolt and nut assembly in place of a standard pin, providing secondary securement for permanent or high-vibration rigging applications.
  • Controlled Manufacturing Tolerances: Standards maintain a ±5% tolerance for both the jaw opening (W) and pin diameter (øP) to ensure a precise site fit.
  • Rapid Adjustment: The wedge-style design allows for efficient field installation and easy rope adjustment without the need for specialized speltering.

Open Wedge Socket (Bolt & Nut) Technical Specifications

Below is a selection of technical specifications for the OWS-B series. Please contact our technical team for full dimensional details (A, B, C, TB, WH, WB, WD) and MBL verification based on your specific rigging requirements.

⚠ Safety Warning: Always adhere to the Minimum Breaking Load (MBL) and ensure the wire rope is correctly terminated by qualified personnel. Surface finishes like hot-dip galvanizing or paint may slightly increase overall thickness and jaw dimensions; always verify fit-up on site. Refer to the comprehensive safety documentation on pages 136-149 for full maintenance and installation procedures.
