Facom 11 x 13 mm Obstruction Wrench
The Facom FM-57.11X13 is a double-ended box wrench with 11 mm and 13 mm 12-point heads. It is made from alloy steel with a satin finish. The 30-degree offset and slim 5/16 in head thickness allow access to fasteners in tight or recessed locations. This hand tool suits mechanics and technicians working on automotive or industrial assemblies.
Offset Access Limits
The 30-degree offset angle and 6 1/2 in overall length define the reach and swing clearance available in confined spaces. The 12-point box ends engage fasteners at smaller rotation increments than 6-point designs, but they apply torque to the corners rather than the flats. The wrench is not tether capable, so it cannot be secured for drop-prevention systems required at height.
Check Fastener Size and Clearance
Verify that the fasteners you intend to turn are exactly 11 mm and 13 mm metric sizes. Confirm that the 5/16 in head thickness and 30-degree offset fit the recess depth and surrounding obstacles on your specific job. Ensure a non-tetherable tool meets your site safety requirements before ordering.

Questions about this item
Which size of the Facom FM-57.11X13 should I choose for an 11 mm or 13 mm fastener?
This single wrench has two fixed box ends, one 11 mm and one 13 mm, so it covers both metric sizes without needing a set.
What does the 12-point box end mean when I am working in a tight engine bay?
The 12-point geometry engages the nut every 30 degrees of rotation, giving more engagement positions than a 6-point wrench.
How does the 30-degree offset affect access on a flat surface?
The heads are offset 30 degrees from the handle, letting the box ends reach recessed fasteners while your hand clears surrounding parts.
