CM Super Strong Bolt, Nut & Cotter Shackles are carbon-type shackles with strength ratings that are 17 to 50% stronger than comparable-sized carbon shackles. As a result, these shackles are designed with a 6:1 design factor. Anchor shackles can be sideloaded or used for multiple connections.

• Manufactured from technically advanced micro-alloy steel with optimal hardness for strength and ductility.
• Shackles show major deformation before failure
• The working load limit and traceability codes are shown as permanent markings on the body
• All shackles have alloy quenched and tempered pins
• Available in sizes 3/16" to 2-1/2" (contact us if what you need isn't online)
• Available finishes include powder-coated, galvanized, or self-colored (contact us if what you need isn't online)
• Shackles meet dimensional requirements and exceed performance requirements of RR-C-271
• Note: Screw pin and bolt/nut/cotter shackles have a 6:1 design factor. Round pin shackles have a 5:1 design factor.
