55 mm 12-point offset wrench

The Gray Tools 66555 is a 55 mm combination wrench with a 12-point opening and a 45-degree offset head. It is forged from premium tool steel and finished with a corrosion-resistant black oxide coating. The precision-broached jaws deliver a tight, secure fit on large fasteners. An add-on leverage bar can be installed to increase torque on stubborn bolts.

Mechanics needing high torque on 55 mm hex

This wrench suits technicians who work on heavy equipment, industrial machinery or large vehicle suspensions where a 55 mm fastener is common. The offset head and optional leverage bar provide the mechanical advantage needed for seized or overtightened bolts. Buyers who require a different hex size or a straight-pattern wrench should look at other options.

12-point drive with 45° offset head

The 12-point configuration allows engagement at twelve positions per turn, while the 45-degree offset clears obstructions around the fastener. Together they determine whether the tool can reach and turn the bolt in the available space. Verify the hex size and clearance before purchasing.

Questions about this item

How do I install the add-on bar on this 55 mm 12-point wrench, and what step is commonly missed?

Slide the bar over the handle until it seats fully against the 45° offset head; the step often missed is confirming the bar locks flush so the drive cannot twist under load.

What maintenance will this strike-free leverage wrench need over time?

Wipe the black oxide finish clean after each use and apply light oil to prevent corrosion; inspect the 12-point broach for rounding before every high-torque job.

What limit appears first when using this 66555 wrench continuously on stubborn fasteners?

The 12-point drive will round the fastener corners before the forged tool steel yields, so fastener damage is the practical limit under sustained force.
