1-1/4 in. 12-Point Striking Wrench

The Gray Tools 66840 is a 1-1/4 inch, 12-point striking face box wrench built for heavy-duty fastening. Its 45° offset head provides clearance around obstructions in industrial maintenance and construction. The forged premium tool steel construction meets ANSI standards for professional use.

Offset Head and Striking Block

The 45° offset head design allows access to fasteners in confined spaces without removing surrounding components. A large, robust striking block ensures maximum surface contact and safety when impact force is applied with a hammer. The precision broached opening delivers a tight, secure fit on the fastener.

Capacity and Application Limits

This wrench comfortably handles high-torque loosening and tightening on 1-1/4 inch fasteners found on heavy machinery and structural steel. The corrosion resistant black oxide finish protects the tool in harsh environments. It is not suited for smaller fastener sizes or applications requiring a ratcheting mechanism.

Questions about this item

How do I verify the 12-point box end is engaging the fastener correctly after positioning the 45° offset head?

The precision-broached 12-point opening should seat fully on the fastener with no visible gap; the black oxide finish will show even contact marks across all points when struck, confirming a tight, secure fit.

What comes with the 66840 striking wrench and what must I supply separately?

The wrench itself is the only item included; you will need to provide a suitable striking hammer and the fastener you intend to turn.

Which hex size should I select for a 1-1/4 inch fastener?

Choose the 1-1/4" hex size — it is the single size this model is manufactured to fit.
