The Snap-on 2-1/4" 12-Point SAE Flank Drive® Heavy-Duty Offset Box Tubular Wrench (Model X720B) is a premium professional-grade tool designed for demanding industrial applications. This versatile wrench features a unique dual-function design that allows it to be used independently or with an optional handle for enhanced leverage and reach.

The offset box design provides optimal turning clearance in tight spaces, making it ideal for heavy-duty fleet maintenance, aerospace applications, and industrial environments. The 12-point configuration offers versatility in fastener engagement, while the SAE sizing ensures compatibility with standard American fasteners. A precision detent on the wrench shaft automatically aligns the locking button with the handle hole for seamless attachment.
This heavy-duty tool meets the stringent requirements of professional mechanics, maintenance technicians, and industrial workers. Built to withstand extreme working conditions, the X720B combines durability, functionality, and precision engineering. The wrench is compatible with Snap-on's 36B handle system, allowing users to customize their tool setup based on specific job requirements.
