The Lokrite Hands-Free Magnetic Backup Wrench is a revolutionary tool for bolting, torqueing, and breakout work. This innovative wrench eliminates the need for a second person to hold a backup wrench during operations, making the job safer and more efficient.
Each Lokrite wrench is magnetic, pinch-point free, and equipped with a tension release bolt for easy removal after use. The SMP Lokrite specification sheet provides torque ratings for every size and style of wrench to ensure proper performance and safety.
Lokrite backup wrenches are lighter and easier to carry than conventional wrenches, and they can be equipped with tie-offs and tethers for added fall protection. The open-end Lokrite design is especially useful in tight spaces where a full box-end wrench cannot fit. These open-end tools also feature a locking safety cleat to keep the wrench securely in place during use.
Every Lokrite wrench incorporates patented embedded magnet technology, ensuring a strong, reliable hold without manual support. Standard sizes are available from 1-1/4” to 6-1/8”, with metric options also offered. Custom sizes and styles can be manufactured upon request.
When performing bolting, torqueing, or breakout work, the Lokrite Hands-Free Magnetic Backup Wrench from SMP delivers superior safety, convenience, and efficiency—saving time and reducing the risk of injury on the job.
