Sockets
Open Spelter Sockets With Bolt and Nut
Specifies the OSS series configured with a bolt and nut for maximum retention security. Maintaining the same capacity range (9 to 3527 UStons MBL) and wire diameter compatibility as the pin version, this datasheet provides specific physical parameters for the bolt assembly (TB and OP), ensuring compliance with EN 10204 material certification standards.
Engineered for Ultimate Structural Integrity: High-Performance Open Spelter Sockets with Bolt & Nut
The Open Spelter Socket with Bolt and Nut is a premier securement solution designed for high-capacity structural rigging and permanent wire rope terminations. Manufactured from quenched and tempered cast steel, these sockets feature a secure bolt and nut fastening system, providing an enhanced level of security for critical lifting operations in maritime and industrial environments.
Maximum Safety Features
- Quenched and Tempered Steel: Body is constructed from high-grade quenched and tempered cast steel to ensure maximum durability and fatigue resistance.
- Exceptional Load Capacity: Standard models offer a Minimum Breaking Load (MBL) ranging from 9 UStons up to 3527 UStons.
- Standard-Certified Quality: Every socket is provided with an EN 10204-2.1 declaration of conformity and an EN 10204-3.1 material certificate.
- Durable Corrosion Protection: Finished with a standard blue primer coating and hot-dipped galvanizing (Note: OSS 196 through OSS 100 are galvanized only).
Industrial Versatility & Precision
- Broad Wire Rope Compatibility: Engineered to accommodate wire rope diameters from 1/4″ to 8″ and strand diameters from 1/2″ to 7-1/2″.
- Secure Fastening System: Utilizes a heavy-duty bolt and nut assembly to prevent unintended pin release during high-vibration or long-term structural use.
- Precise Tolerances: Manufactured with dimensional tolerances of ±5% for the jaw opening (W) and pin diameter (ØP).
- Application Flexibility: Ideal for bridge construction, offshore mooring, and high-capacity crane rigging where permanent securement is required.
Open Spelter Socket (Bolt & Nut) Technical Specifications
Below is a partial specification table for OSS-B models. Please contact our technical team for full dimensions (A, B, C, D, H, T, TB) and MBL verification based on your specific wire rope or strand requirements.
⚠ Safety Warning: Always adhere to the Minimum Breaking Load (MBL) and ensure that the wire rope or strand is properly speltered by certified personnel. Be aware that surface finishes such as paint or galvanizing may slightly increase overall thickness and jaw dimensions. Refer to the comprehensive safety documentation on pages 136-149 for full inspection and speltering procedures.
