GearWrench 10-Piece SAE and Metric 72-Tooth Ratcheting Combination Wrench Set
The GearWrench 9418 is a 10-piece SAE and metric ratcheting combination wrench set featuring a 72-tooth box end mechanism that requires just a 5-degree swing arc to turn fasteners compared to the 30-degree arc of standard wrenches. Engineered for automotive technicians, industrial mechanics, and machinery repair specialists working in cramped engine bays, this alloy steel set utilizes off-corner loading geometry on its 12-point box ends to shift clamping force to fastener flats and eliminate head rounding on stubborn bolts.
Best Used For:
- Automotive Engine Bay Maintenance: Reaching tight serpentine belt tensioners, alternator bolts, and intake manifold hardware in confined engine compartments.
- Industrial Machinery Assembly: Turning metric and SAE hex fasteners against flat surfaces using the 15-degree box end offset for knuckle clearance.
- Equipment and Fleet Service: Removing rusted or stubborn 12-point and 6-point fasteners without rounding bolt corners due to off-corner loading technology.
Key Performance & Safety Features
- 5-Degree Swing Arc: Precision 72-tooth ratcheting box end turns fasteners in tight spaces where standard 30-degree swing wrenches cannot operate.
- Off-Corner Loading Design: Directs torque to the flat sides of hex heads rather than the corners to prevent fastener rounding and damage.
- 15-Degree Box End Offset: Provides critical hand and knuckle clearance when working flat against engine blocks and equipment housings.
- Forged Alloy Steel Construction: High-strength steel alloy formulation engineered to exceed ANSI torque specifications under heavy manual leverage.
- Full Polish Chrome Finish: Smooth exterior plating offers high resistance against chemical corrosion, rust, and jobsite oil buildup for easy cleanup.
- Sleek Profile Head: Slim box and open end designs deliver maximum access to recessed or obstructed hardware.
