Professional 12-Point Wrench

The Gray Tools 3172 is a 2-1/4 inch combination wrench built for heavy-duty fastening tasks. Its 12-point box end engages fasteners at multiple angles for efficient work in confined spaces. Professional mechanics and industrial maintenance crews rely on this sizing for large equipment bolts. It is not suited for buyers who need smaller hex dimensions for light assembly.

The satin chrome finish provides maximum resistance against corrosion during daily shop exposure. Precision broaching ensures a tight, secure fit on fastener flats to reduce rounding risk. The wrench meets ANSI standards for dimensional accuracy and strength. No alternative finish or coating options are offered for this model.

Questions about this item

How does the 2-1/4" hex size determine which fasteners this wrench fits?

It fits only fasteners with a 2-1/4" hex size; the 12-point broach gives multiple engagement angles for a secure grip on that specific dimension.

What does the ANSI standard cover for this 12-point wrench?

ANSI standards govern dimensions, hardness and performance so the wrench meets recognised quality and safety benchmarks for hand tools.

What space is needed to use the satin chrome finish wrench effectively?

The box end requires clearance around a 2-1/4" hex head, while the open end needs side access to slide onto the fastener flats.
