Embedded Magnets
The back-up wrenches are held in place with embedded magnets, this allows hands to remain clear of any pinch points or high force areas.
Release Screw
Once the fastener is tight, the backup
wrench can be safely removed with no residual load by releasing the release screw.
Wide Range of Applications
Extensively used with ANSI and API flanges, it can also be used in any bolting application that involves nuts, bolt heads & studs.
High Strength
Heat treated steel for better performance and tensile strength.
Bi-hexagonal Design
The bi-hexagonal design allows for greater positioning options.
