From the Manufacturer

Snap-on Industrial Brand JH Williams 20 millimeter super combo combination wrench is a metric wrench with a high polish chrome finish and 12 point box end. The wrench has a super combo open end as well as a super torque box end. The open end has specially designed grooves that direct wrench force away from fastener corners. The super torque box opening design allows application of higher torque without rounding or deforming hex fastener points. No contact is made at the corners. Instead, wrenching forces are placed on the flat surfaces behind the points. It may be used on all common hex 6 point fasteners with considerable advantage over conventional box end wrenches to increase both hand tool flexibility and economy. The box and open end openings are identical.
.OPEN-END DESIGN: Precision-cut grooves redirect force away from fastener corners to reduce rounding and slippage, providing a steadier, more controlled grip that performs consistently during repeated use and higher-torque applications.
.12-POINT BOX END: Specialized geometry applies torque to the flats of the fastener rather than the edges, delivering stronger turning power with less risk of damage and smoother, more reliable engagement in tight or hard-to-reach spaces.
.HIGH-STRENGTH ALLOY STEEL: Crafted from durable alloy steel with a polished chrome finish that resists rust, corrosion, and general wear, ensuring dependable longevity and maintaining a clean, professional look throughout heavy, daily use.
.COMPATIBLE WITH HEX FASTENERS: Though built as a 12-point box end, it securely fits standard 6-point hex fasteners, offering broader versatility and significantly reducing extra tool changes during automotive, industrial, or maintenance-focused tasks.
.ACCURATE METRIC SIZE: This wrench provides a precise 20 mm fit with easy-to-read size markings for quick, effortless identification, making it an excellent choice for technicians working on compact assemblies or detailed mechanical work.
