80 mm 12-point offset wrench

The Gray Tools 66580 is a hand wrench built for large and stubborn fasteners. Its 80 mm 12-point head provides a secure fit on compatible hardware. The 45-degree offset improves access in confined spaces. It suits mechanics and maintenance workers who need high torque on big bolts.

Installing the add-on bar and common issues

An add-on bar installs onto the wrench to multiply leverage for tighter fasteners. The precision broached opening reduces rounding when the bar is used correctly. Corrosion resistant black oxide finish protects the tool during storage. Applying force at extreme angles without the bar can damage the head.

Checks before ordering

Verify the fastener measures exactly 80 mm across the flats before purchase. Confirm a 12-point drive matches the bolt or nut geometry you encounter. Ensure the 45-degree offset clears surrounding components in your work area. The product carries a California Proposition 65 warning for chemical exposure.

Questions about this item

How can I confirm the 80 mm 12-point offset head is engaging the fastener correctly after setup?

The precision-broached 12-point opening should seat fully on the fastener without play; the 45-degree offset keeps the handle clear so you can see the fit and feel positive contact.

What comes in the box with the 66580 wrench and what must be purchased separately?

The wrench itself is supplied; the add-on leverage bar that increases torque is sold separately.

Which version of the 80 mm 12-point offset wrench should I choose for maximum durability?

The 66580 is forged from premium tool steel with a corrosion-resistant black oxide finish and meets ANSI standards for heavy-duty use.
