Types of Terminations for Stainless Steel Wire

Introduction

Stainless steel wire is widely used in rigging, lifting, and structural applications, requiring secure and reliable terminations. The termination method depends on strength requirements, flexibility, and installation conditions. Below are the most common types of wire terminations.

Common Wire Termination Methods

1. Swaged Terminations

• Process: A fitting is permanently attached using hydraulic pressure.

• Examples: Swaged eyes, swaged threaded studs, and swaged sockets.

• Advantages: Strong, compact, and ideal for standing rigging.

• Disadvantages: Requires specialized equipment for installation.

2. Mechanical Terminations (Sta-Lok, Norseman)

• Process: Fittings are secured using wedges and threaded components.

• Examples: Sta-Lok and Norseman terminals.

• Advantages: Can be installed without heavy machinery.

• Disadvantages: Bulkier than swaged fittings and more expensive.

3. Wire Rope Clips (U-Bolt or Double Saddle)

• Process: A U-bolt and saddle clamp the wire to form a loop.

• Examples: Crosby wire rope clips.

• Advantages: Simple and adjustable.

• Disadvantages: Lower strength and requires multiple clips for security.

4. Flemish Eye Splice

• Process: Wire strands are unlaid, re-woven, and secured with a swaged sleeve.

• Advantages: High strength and widely used in lifting applications.

• Disadvantages: Requires precise execution for reliability.

5. Wedge Sockets

• Process: A wire is inserted into a socket with a wedge that tightens under load.

• Advantages: Adjustable and reusable.

• Disadvantages: Less secure than swaged or mechanical fittings.

6. Poured Sockets (Resin or Molten Zinc)

• Process: The wire is inserted into a socket and secured with molten zinc or resin.

• Advantages: Extremely strong and durable.

• Disadvantages: Requires specialized materials and curing time.

Choosing the Right Termination

• Marine Rigging: Swaged or mechanical fittings for durability.

• Lifting Applications: Flemish eye splices or poured sockets for maximum strength.

• Temporary Use: Wire rope clips or wedge sockets for adjustability.

Conclusion

Selecting the right termination depends on strength, durability, and installation requirements. Whether for yacht rigging, industrial lifting, or architectural structures, understanding these options ensures safe and effective wire applications.
