RAT COMB XL SPLINE #10X5/16" GEAR WR* - GearWrench

Part #: 85550D

The GearWrench 85550D Ratcheting Combination Extra Long Spline Wrench is engineered for professional technicians and mechanics requiring superior access and performance in demanding work environments. This versatile tool features a unique spline drive on both its #10 and 5/16-inch ends, designed to engage with multiple fastener types, providing efficiency and adaptability on the job. Its extra-long beam construction ensures greater reach and leverage, making it an indispensable addition to any professional toolkit.

Key Features

  • Universal Spline Drive: The innovative spline drive system allows this wrench to work effectively on 12-point, 6-point, rounded 6-point, spline, External Torx®, and square fasteners, significantly increasing its versatility.
  • Extra-Long Beam Design: An extended handle length provides enhanced leverage and reach, making it easier to break loose stubborn fasteners and access components in confined or deep-set locations.
  • Efficient Ratcheting Mechanism: The ratcheting box end is designed for rapid fastener engagement and release, with many GearWrench ratcheting wrenches featuring a high tooth count for a minimal swing arc, enabling work in extremely tight spaces.
  • Off-Corner Loading: The box end employs an off-corner loading design, which grips the flats of the fastener rather than the corners, reducing the risk of fastener rounding and prolonging fastener life.
  • Durable Construction: Manufactured from robust alloy steel with a full polish chrome finish, this wrench offers exceptional strength, longevity, and resistance to corrosion, ensuring it stands up to rigorous daily use.

Applications

The GearWrench 85550D is ideal for a broad range of professional applications, including general automotive maintenance and repair, industrial machinery servicing, and equipment assembly. Its extra-long design is particularly beneficial for reaching fasteners in engine bays, undercarriages, and other areas with restricted access. The spline drive capability makes it suitable for working on diverse fastener types commonly encountered in various mechanical systems.
