Apex 85578 Ratcheting Combination Wrench 9/16 Inch 12 Point

Product Description

The APEX 85578 is a combination open-end ratcheting wrench sized at 9/16 inch with a 12-point box end. It is designed for use in fastener work where standard wrenches slow the job down. The open end delivers the holding strength of a crows foot ratchet, while the box end ratchets with a five-degree swing arc. That tight arc lets techs drive nuts and bolts in confined spaces without lifting and repositioning the wrench on every stroke. At 0.31 pounds and 7.504 inches in length, it is a practical hand tool for daily use in any trade.

This wrench suits residential and commercial service work across HVAC, plumbing, electrical, and mechanical trades. It performs well in panel work, equipment installations, and maintenance tasks where fastener access is restricted. The ratcheting action on both ends eliminates the need to break contact with the fastener mid-turn, reducing time on repetitive tightening or loosening tasks. Sold individually.

Installation Notes

This wrench is used by HVAC technicians, plumbers, electricians, and general mechanical trades. Always de-energize electrical equipment and shut off fluid or gas supply before servicing fastened connections.
