Columbus McKinnon Super Strong Alloy-Pin Screw-Pin Bow Shackle for 4WD Recovery
Add a Columbus McKinnon screw-pin bow shackle to a compatible 4WD recovery setup. The removable screw pin allows for quick attachment and removal. Choose the shackle by its stamped Working Load Limit (WLL), material, and compatibility with every component in the recovery system.
FEATURES
- Columbus McKinnon Super Strong screw-pin bow shackle
- Alloy quenched-and-tempered pin
- 6:1 design factor
- Permanent WLL and traceability markings on the shackle body

SIZE AND FITMENT GUIDANCE
The 3/4-inch screw-pin bow shackle is a common size in 4WD recovery. A standard-duty 3/4-inch shackle with a 4.75-ton WLL may be appropriate for some 1/2-ton truck setups. For 3/4-ton and 1-ton truck applications, Freedom Recovery Gear recommends the CM alloy-pin shackle. The listed CM 3/4-inch alloy-pin variant has a 6.5-ton WLL.
This is general fitment guidance, not a substitute for checking the vehicle, recovery points, and ratings of the complete system. Always follow the WLL marked on the specific shackle.
MBS AND WLL DEFINITIONS
MBS means Minimum Breaking Strength: the lowest amount of force or load a product or component can withstand during controlled laboratory testing before it structurally breaks or fails.
WLL means Working Load Limit: is the maximum safe load that a piece of rigging equipment is designed by the manufacturer to handle during normal, everyday use. It is much lower than the force required to make the equipment fail or yield.
SAFETY
- Inspect the shackle and pin before each use. Do not use damaged, deformed, excessively worn, or unmarked gear.
- Use only the original manufacturer-supplied pin. Fully seat it, and make sure it cannot loosen in the application.
- Keep the load aligned through the centerline of the bow and pin. Avoid side loading.
- Do not shock load or use for kinetic or snatch recovery.
- CM warns that screw-pin shackles should not be cyclically loaded and that torque or twisting can cause a screw pin to back out. Use only in configurations permitted by the manufacturer.
- Never exceed the shackle’s stamped WLL or the rating of any other component in the recovery system.
- If you are not trained to use recovery equipment, seek instruction from a qualified professional before use.
ADDITIONAL INFORMATION
- Finish and color may vary.
- Specifications are subject to change without notice.
