Description
A single-unit, dual-direction mechanical torque wrench with a high-resolution micrometer scale that’s easy to read and lock in place but requires being set to the minimum value when storing. It’s an affordable combination of accuracy and mechanical reliability.
Apply Torque with Confidence
Every feature was designed to instill confidence in the wrench’s accuracy and control during operation.
Calibrated to be accurate within ±3% for both clockwise and counterclockwise directions
Certified to the ISO standard for the full listed range (40 – 300 ft-lb), unlike torque wrenches calibrated to ASME standards, which do not require calibration below 20% of the listed range
90-tooth ratchet head with minimal swing arc (4° per tooth)
Accurate micrometer scale with high-contrast markings
Locking collar for a positive hold on the target torque setting
Coarse handle knurling and centerline groove for a sure grip
Accurate Within ±3% for Both Directions
The actual calibration accuracy will be stated on the certificate for your wrench and will be within ±3%.
90-Tooth Fixed Ratchet Head
The single half-moon pawl maintains 9 teeth engaged with the gear at all times, so it won’t skip under stress. The internal components are the same design and construction as all of the 90-tooth ratchets.
4º Swing Arc Reduces Length of Travel
Having more teeth in the ratchet (B) results in less travel at the end of the wrench handle (D) between each tooth click.
Easy-to-Read Micrometer Scales
Single-unit scale for simplicity (ft-lb)
High-contrast laser markings with bold fonts
Satin finish on the body to reduce glare
Numbers on the main scale are positioned close to the centerline to be readable without rotating the wrench
Indicator lines on the main scale are straight, not offset
Spring-Loaded Collar Locks Your Setting
The collar springs into a locked position that holds your setting and prevents accidental movement during operation. There is no thumb knob to tighten at the end of the handle.
Coarse Knurling for a Secure Grip
A deep, sharp-cut diamond pattern on the surface of the handle creates a coarse texture that wont slip in your hand.
Full-Featured Case
The case provides safe transport for the torque wrench and protects it from drops. Each item in the case has it’s own place and is held securely. The case is made of high-density polyethylene (HDPE) and the latches are polypropylene (PP).
Removable lid for shallow drawers
Top and bottom tracks allow stacking
Textured surfaces provide a firm grip
Hard plastic latches
Removable metal hinge pins
