Order the GearWrench 85921 GearBox XL 12 Pt. Double Box Ratcheting Wrench, 21mm for $23.85 — half off the $47.69 compare-at price. Use a 21mm GearBox XL wrench to break loose stubborn, rusted fasteners with long-pattern torque, then ratchet them free in as little as 5 degrees of swing.
GearWrench 85921 vs. Standard Combination Wrench
A standard 21mm combination wrench needs 30 degrees of swing and offers no ratcheting. The 85921's standard box end delivers maximum breakaway torque from the long pattern length, while the ratcheting box end spins the fastener off quickly once it's free — two tools in one.
