The ideal solution for aerospace fastener retention: Bergen Safety Cable

Safety Cable has been the standard since 1987.

Bergen Cable has been a major supplier of cable solutions for nearly eight decades, and a highlight of the company’s illustrious history is its participation in the development of Safety Cable. A convenient alternative to lock wire, Bergen Safety Cable is an essential fastener-retention system for the aerospace industry.

For more than 30 years, this cable solution has been the safest, most cost-effective, and most easy-to-install option in the industrial cable market for quicker retention.

In collaboration with General Electric

Bergen Safety Cable became a reality in 1987, when the company developed it in collaboration with General Electric Aircraft Engines. GE and Bergen tested this new cable at the former’s plant and found that it lowered installation time by half, provided higher quality, and reduced assembly expenses. In the years since, Safety Cable has become the aerospace sector’s standard solution for fastener retention.

The four main elements of Bergen Safety Cable:

• Safety Cable tool. Bergen has cable tools with diameters of .022, .032, or .04 and nose lengths of three, five, or seven inches. These tools come with 360-degree rotating noses that enable easier use in nonstandard positions.
• Safety Cable. Lengths run from nine to 36 inches. Materials include 304 or 321 stainless, Inconel 600 for high-temperature or non-magnetic applications, and Inconel 625 for anti-corrosion protection. Bergen recommends self-looping cable for fasteners without holes. Filler washers are available for fasteners with oversized lock-wire holes.
• Ferrules. A spring-loaded magazine containing 50 ferrules is available. These come in the same materials and diameters as the cable does. Bergen also offers elongated ferrules that allow proper retention of fasteners with limited clearance.
• Accessories. Torque blocks for periodic verification of tool settings to ensure correct tool operation quickly; precision torque wrenches for use with torque blocks; cutter gripper tools for removing cable and lock wire safely and efficiently; and electronic load testers for tension and ferrule pull-off tests.
