Professional 34 Drive Torque Wrench 100 to 600 ft Lbs Heavy Duty Tool
GEARWRENCH 3/4-Inch Drive Micrometer Torque Wrench, 100–600 ft-lb
The GEARWRENCH 3/4-Inch Drive Micrometer Torque Wrench is a heavy-duty torque tool designed for applications where large fasteners require controlled and repeatable torque. With a broad 100–600 ft-lb torque range, this wrench is well suited for heavy trucks, construction machinery, agricultural equipment, industrial maintenance, and other demanding mechanical applications.
Its micrometer-style adjustment system makes it possible to set the desired torque directly on the wrench, while the twist-locking collar helps keep the selected setting secure during use. A 36-tooth ratcheting mechanism provides a 10° swing arc, allowing the wrench to operate in areas where a larger swing would be difficult.
Key Features
3/4-inch square drive for high-torque fastening applications.
100–600 ft-lb torque range for large fasteners and heavy-duty service work.
Equivalent alternate range of approximately 152.6–830.6 Nm.
±3% clockwise torque accuracy from 20% to 100% of the wrench's full scale.
36-tooth ratchet mechanism with a 10° swing arc.
Twist-locking collar helps maintain the selected torque setting.
Highly visible scale markings make torque settings easier to read.
Elastomer handle provides a comfortable, secure grip.
Oil- and solvent-resistant handle helps withstand common workshop exposure.
Full-polish chrome finish provides a durable professional appearance.
Includes a blow-molded storage case.
Meets or exceeds ASME B107.300 requirements.
Backed by a 1-year limited warranty, with calibration accuracy warranted for 90 days.
High-Torque Performance
The 100–600 ft-lb range places this wrench firmly in the heavy-duty category. It is intended for large fasteners where a smaller torque wrench would not provide sufficient capacity.
Common applications include:
Heavy trucks
Construction equipment
Agricultural machinery
Industrial equipment
Large mechanical assemblies
Fleet maintenance
Heavy-duty automotive service
The 3/4-inch drive accepts compatible 3/4-inch drive sockets and accessories, making it suitable for larger fastening systems.
Micrometer-Style Torque Adjustment
The micrometer design allows the user to set the desired torque by adjusting the handle to the required value on the wrench's scale.
Once the desired setting is selected, the twist-locking collar helps prevent unintended adjustment while the wrench is being used. This is particularly useful in repetitive maintenance work where consistent torque settings are important.
Accurate Torque Control
GEARWRENCH specifies ±3% clockwise accuracy from 20% to 100% of full scale. This provides controlled torque application across the usable portion of the wrench's rated range.
For applications where manufacturers specify a precise fastener torque, using a properly set and maintained torque wrench helps technicians achieve the required tightening specification more consistently.
36-Tooth Ratcheting Head
The 36-tooth ratchet mechanism provides a 10° swing arc. This allows the wrench to engage and turn fasteners without requiring a full handle rotation.
The ratcheting head is useful in workshop environments where surrounding components or equipment limit available movement.
Easy-to-Read Scale
The torque scale markings are designed to be highly visible, helping users identify and set the required torque value more easily.
The primary scale is graduated in 2.5 ft-lb increments, while the alternate metric scale covers approximately 152.6–830.6 Nm with 3.4 Nm increments.
Durable Workshop Construction
The wrench is constructed from alloy steel and features a full-polish chrome finish. Its elastomer handle provides a comfortable grip, while the handle material is designed to resist oil and solvents commonly encountered in automotive and industrial environments.
Storage Case Included
A blow-molded storage case is included with the wrench. The case provides a dedicated place to store and transport the tool when it is not in use, helping protect the torque wrench from unnecessary impacts and workshop damage.
