21mm Combination Wrench – Professional-Grade Tool for High-Volume Shops

This 21mm combination wrench delivers the dual functionality your technicians need: an open U-shaped jaw on one end for accessibility in tight spaces, paired with a 12-point ring head on the opposite end for secure, multi-angle grip on bolt heads.

Built for shops that demand reliability without compromise, this wrench handles routine fastening tasks across automotive, industrial maintenance, and assembly work. Whether your team is working with metric-standard hardware or maintaining mixed-equipment fleets, having properly sized wrenches in your inventory ensures faster job completion and reduces the frustration of makeshift solutions.
